Published: October 2024

¿Te gusta ir a eventos que organizan los mismos alumnos?, ¿vas en contra del sistema educativo de tu preparatoria?, ¿tienes metas, pero no sabes cómo alcanzarlas?, ¿eres muy talentoso en algo, pero no sabes cómo desarrollarlo?, quizás seas tu un nini. Los ninis abundan en todos lados, y la ENMS no es la excepción, pero, realmente ¿son ninis? ¿acaso algunos ocultan algo? Los ninis o más bien sus características de ellos son: personas que no aportan nada a la sociedad y un nini funcional es que puede que llegue a aportar algo pero no es una forma muy eficiente o por ende pueden dar más pero no lo aprovecha; con esta opinión queremos dar a notar algunas causas o motivos junto con pequeñas soluciones de las cuales se generan los ninis funcionales, hablando de otras formas, quizá algunos presentan desafíos y oportunidades que no son capaces de lidiar y se vuelven lo que nosotros conocemos como ninis funcionales, siendo, ejemplos muy precisos, lo que la mayoría enfrentan como lo son problemas, diferencias, incluso oportunidades

El trauma infantil se relaciona con alteraciones en el eje hipotalámico-hipofisario-adrenal (HPA) y una mayor vulnerabilidad a la depresión y enfermedades cardiometabólicas. Durante los años universitarios, el estrés académico y psicosocial puede exacerbar estos problemas. El objetivo del presente estudio es comparar la calidad de sueño y el estrés percibido, la reactividad al estrés agudo y estrés crónico en estudiantes universitarios con y sin eventos adversos tempranos. Se reclutaron 16 estudiantes universitarios para analizar el impacto del trauma temprano en el estrés y el sueño, utilizando muestras de saliva y cabello para medir cortisol agudo y crónico. Los resultados muestran que los estudiantes con experiencias tempranas de trauma presentan mayor latencia al sueño (p=0.03) y niveles más altos de estrés comparados con (p=0.04), comparación con aquellos sin trauma temprano. Por lo que se puede concluir que las experiencias adversas en la infancia alteran la calidad de sueño y el estrés percibido en estudiantes universitarios.

La palabra nomofobia hace referencia a las condiciones psicológicas percibidas por las personas al estar desconectadas de sus teléfonos móviles, siendo más común en adolescentes y adultos jóvenes, especialmente universitarios. Estudios previos mencionan que existe una relación significativa entre el índice de calidad de sueño y la puntuación de nomofobia. Pese al incremento exponencial de esta condición problemática relacionada con el uso del celular, en especial en población joven, no existen estudios en población latina que evalúen dicha relación. El objetivo del presente estudio es evaluar la relación entre el nivel de nomofobia con la calidad de sueño y el estrés percibido en estudiantes universitarios. Se reclutaron 16 estudiantes universitarios para poder analizar el impacto de la nomofobia en el estrés psicosocial y la calidad de sueño, utilizando los cuestionarios de Índice de calidad de sueño de Pittsburgh (PSQI), escala de nomofobia (NMP-Q) y escala de estrés percibido (PSS). Los resultados arrojaron que a mayor índice de renuncia a la comodidad por el uso de teléfono celular y nivel total de nomofobia, es mayor la latencia a quedarse dormido (R2=0.3,p=0.032). Así mismo, la pérdida de comunicación por uso de celular afecta la eficacia del sueño (R=0.17, p<0.11); además, a mayor índice de renuncia a la comodidad por el uso de teléfono celular y mayor nivel total de nomofobia es menor la eficiencia al sueño (R2=0.27, p<0.04). Se puede concluir que los niveles de nomofobia están directamente relacionados con problemas en la calidad de sueño en estudiantes universitarios.

Las pantallas electrónicas para visualizar información en general se erigen como herramientas fundamentales de los estudiantes para acceder a los contenidos que requieren investigar al participar en su proceso de aprendizaje. De igual manera, los docentes necesitan utilizar las pantallas electrónicas para llevar a cabo, fortalecer y enriquecer su proceso de enseñanza-aprendizaje, en la preparación de las clases, presentaciones, trabajos, exámenes y su evaluación. Asimismo, tanto alumnos como maestros utilizan las pantallas para atender cuestiones personales y de entretenimiento; podrían considerarse éstas como un medio imprescindible del devenir de nuestra sociedad. Todo lo anterior, conduce a que en la actualidad tanto los estudiantes como docentes estén empleando las pantallas un promedio de 6 horas al día, en algunos casos más, lo que conlleva la aparición de ciertas molestias en el sentido de la vista, causando en algunas situaciones daños más severos, conduciendo a la necesidad de medir en nuestra comunidad educativa el conocimiento científico que se tiene acerca del SVI, la consciencia de los problemas que un uso inadecuado de las pantallas puede causar y, con base en los resultados de la investigación, promover métodos y hábitos de trabajo saludables en el necesario empleo de las pantallas electrónicas.

Authors: González Portillo Sarai , Rosas Vargas Rocío , León Andrade Marilu
Published: October 2024

En el estado de Guanajuato, la violencia se ha recrudecido en los últimos años. Desde finales de 2016, la violencia, producto de las luchas entre diversos cárteles, se incrementó en casi todos los municipios del estado. Pero en algunos con más virulencia, como Celaya, León, Irapuato y en el sur del estado destaca Salvatierra, Tarimoro y Yuriria. La violencia afecta a todos los ámbitos de la sociedad, a todas las clases sociales, pero hay sectores de la población que suelen ser más vulnerables. En el caso en estudio, sabemos que las y los menores que asisten a escuelas secundarias de zonas con alta violencia pueden verse involucrados en hechos violentos y además podrían desarrollar secuelas ante estas situaciones. El objetivo de este trabajo es conocer qué trabajos de cuidado y autocuidado se realizan al interior de las escuelas secundarias, incluso en sus hogares y comunidades, a donde acuden niños/niñas y jóvenes y donde se podrían llegar a reproducir situaciones como las vividas en las calles de Guanajuato.

El presente escrito aborda la relevancia de las micro, pequeñas y medianas empresas (MIPYMES) en México y principalmente en Guanajuato. Se discuten los desafíos que enfrentan estas empresas, especialmente en relación con la inseguridad, que afecta su operatividad y capacidad de planificación a largo plazo. La inseguridad ha llevado a los empresarios a invertir en medidas de protección, lo que incrementa sus costos operativos y reduce la rentabilidad. En esta investigación se exploran los factores que los empresarios de pequeñas empresas que se dedican a la comercialización de paletas y helados en Celaya, Guanajuato. Se consideran al fijar precios y tomar decisiones financieras, así como la importancia de las redes de contactos y la ética empresarial en su gestión. Se mencionan ejemplos de decisiones difíciles que han impactado la dirección de sus negocios y se discuten problemas financieros que enfrentan para crecer y aprovechar oportunidades. Se realizó una investigación descriptiva con un enfoque mixto a partir de 15 entrevistas y 3 entrevistas semiestructuradas. Los principales hallazgos refieren a que las microempresas tienen un acceso limitado a financiamiento, lo que dificulta su capacidad para gestionar efectivo y acceder a prestaciones, afectando su crecimiento y sostenibilidad. La inseguridad en la región representa una barrera significativa para el crecimiento de estas empresas, obligándolas a invertir en medidas de seguridad que incrementan sus costos operativos. Muchas de las paleterías carecen de una estructura organizativa sólida, lo que dificulta el cumplimiento de tareas de manera formal y afecta la calidad del servicio al cliente. En resumen, el documento resalta la importancia de las MIPYMES en la economía mexicana y los retos que deben superar para prosperar en un entorno incierto.

Authors: Ikezu Tsuneya , Yang Yongjie , Verderio Claudia , Krämer-Albers Eva-Maria
Published: October 2024

Communication between neurons and glia significantly influences the development maturation, plasticity, and disease progressions of the nervous system. As a new signaling modality, extracellular vesicles display a diverse role for robust functional regulation of neurons through their protein and nucleic acid cargoes. This review highlights recent breakthroughs in the research of signaling mechanisms between glia and neurons mediated by extracellular vesicles that are important for neural development, axonal maintenance, synaptic functions, and disease progression in the mammalian nervous system. We will discuss the biological roles of extracellular vesicles released from neurons, astroglia, microglia, and oligodendroglia in the nervous system and their implications in neurodegenerative disorders.
Radicle emergence and seed imbibition tests as estimators of seed vigour in mexican Pepitilla maize landrace
Authors: Estrada-Urbina Juan , Carballo-Carballo Aquiles , Hernández-Livera Adrián , Cruz-Lagunas Blas
Published: October 2024

Seed vigour of Mexican native maize was evaluated in 10 Pepitilla populations (PEP) and three improved varieties by radicle emergence vigour (REVT) and seed imbibition tests, in order to design a plant breeding programme to obtain native varieties with high seed vigour. As part of the
REVT, protrusion percentage (PR), radicle emergence (RE), non-germinated seeds (NGS) and radicle length (RL) were measured. Additionally, the imbibition curve and the percentage of testa rupture were recorded. Radicle protrusion in Pepitilla seed lots was 73-94%; for improved varieties, it
ranged from 69 to 94%. For 'PEP-2401NS', 'PEP-2402AG', 'PEP-2406GU' and 'PEP-2410RP', RE was equal to PR, so, neither of these genotypes produced a radicle < 2 mm; while, RE in 'V 236P' was 50% lower than PR. In addition, the R 2 of 0.9630 between RE and standard germination suggests
that RE can be considered a reliable test to predict maize seed germination. For NGS, 'PEP-2402AG' and 'H-565' showed 6%, and RL in Pepitilla was three times greater than for the improved varieties. After 36 hours imbibition, an improved variety registered the highest water absorption (49.8%),
but all Pepitilla landraces showed higher testa rupture. In general, the Pepitilla populations had a high seed-vigour due to the rapid RE and a greater RL.
Job Insecurity, Employability and Financial Threat during COVID-19
Authors: Greenglass Esther , Fiksenbaum Lisa
Published: October 2024

COVID-19 has resulted not only in widespread illness and death, it has also upended most spheres of social life including the economic/financial one in that it has had large impacts on local economies, resulting in widespread job loss, job insecurity and loss of income. Employability, a psychological construct, refers to the belief that one can get a (another) job in the event of job loss, and financial threat refers to feelings of threat and anxiety associated with one’s finances. During the pandemic, many people experienced job loss due mainly to business closures. The present study examined the relationship between employability, job insecurity due to COVID-19, and financial threat in a Canadian (n= 487) and U.S. (n=481) sample of adults recruited on MTurk early on in the pandemic (April 2020). Participants in the Canadian sample, compared to their American counterparts, were less likely to be employed full-time, 37% vs. 67%, respectively, were more likely to be unemployed, 40% vs. 13%, respectively, and had lower self-reported socio-economic status.  A theoretical model was put forward in which employability was associated with less job insecurity and this was related to less financial threat. Results revealed that financial self-efficacy was associated with greater employability, less job insecurity and less financial threat in both samples. Further, feelings that one had enough income to “get by” since the advent of COVID-19, were positively related to employability in both samples, but in the Canadian sample only, these feelings were also related to less job insecurity and less financial threat. Implications of the study’s results are discussed within the economic climate resulting from the pandemic.
On-line Booking and Revenue Management: Evidence from a Low-Cost Airline
Authors: Alderighi Marco , Piga Claudio A.
Published: October 2024

Using unique data on a low-cost airline posted prices and seat availability, this study sheds
some light on whether the airline’s actual practice of yield management techniques conforms
with some predictions from economic models of peak-load pricing under demand
uncertainty. On the one hand, robust support is found to the notion that prices increase
as the seat availability decreases; on the other, theoretical models that do not account for stochastic peak-load pricing fail to capture an important source of dispersion in the data.

Plataformas de mídia social, como o Twitter, funcionam como meios de cognição, comunicação e cooperação, possibilitando a prática comunicacional conflitiva de constituição e redefinição constante de sujeitos, suas ações e formas de agenciamento. Nos últimos anos, pesquisas constataram indícios de que a extrema direita ganhou força nesses espaços digitais. Contudo, essas produções prescindiram de uma revisão bibliográfica adequada sobre as características ideológicas da extrema direita e, mais especificamente, da extrema direita no Brasil. A proposta deste trabalho é suprir essa lacuna. Propomos uma estratégia metodológica que se divide em duas partes. Primeiro, fizemos uma revisão bibliográfica sobre os mais recentes trabalhos acerca da extrema direita. Em seguida, utilizamos a metodologia de análise de traços digitais, a fim de identificar os elementos identitários da extrema direita brasileira no Twitter. Os achados vão ao encontro da literatura especializada sobre a extrema direita, confirmando os mesmos traços identitários dos atores políticos identificados por meio de outras abordagens metodológicas.
Impact of Lactobacillus rhamnosus GG fermentation on shelf life of Volvariella volvacea paste
Authors: Alam H. , Kaur J. , Sharma S.
Published: October 2024

Paste formulations of Volvariella volvacea (VV) were developed for its shelf-life enhancement. Egg stage fruiting bodies of mushrooms were used for preparation of salted, spiced, and their fermented pastes. Fermented paste formulations were developed using inoculation with Lactobacillus rhamnosus GG at 0.5% (w/w) and incubation for 2 days at 35 ± 2 °C. The unfermented VV paste was preserved with sodium benzoate of 0.065%, while fermented formulations were kept devoid of any chemical preservative. All formulations were packed in glass jars and retort bags, and thereafter treated in boiling water bath for one hour. The spiced, fermented VV paste scored highest in sensory evaluation and maximum crude protein and moisture contents, while lowest in contents of ash, fat, crude fibre, and carbohydrates. The fermented (salted and spiced) VV pastes showed variation in pH at 4 °C. Shelf life of 56 days was observed for fermented VV paste stored in glass jars under refrigerated conditions. The antioxidant analysis revealed that DPPH radical scavenging activity of fermented paste formulations increased significantly up to 21 days followed by gradual decrease until the 56th day, while total phenolic content of all paste formulations decreased with storage time. Hence, fermented spiced paste showed enhanced nutritive and antioxidative potential and shelf life up to 56 days.

One of the main duties of the harbor master is to issue sailing approvals to ensure order and security of the ship and crew when sailing at sea. The sailing approval letter is a state document issued to every fishing vessel that will sail by the harbormaster. The uncertainty of time, schedule and so on in processing the issuance of the sailing approval letter indicates the importance of having a clear flow and procedure in issuing the sailing approval letter. This research aims to find out the procedures for issuing a sailing approval letter. The research was carried out in May - June 2023. This research was carried out at the Mayangan Coastal Fishing Port (CFP). Data collection was carried out using the observation method and analyzed using a qualitative approach. The procedure for issuing a sailing approval letter at CFP Mayangan is quite good. However, there is still a need for improvement and enhancement in the issuance of sailing approval letter in Mayangan. These include improvements to the application system in order to expedite the application process, socialization to fishermen or sailing approval letter applicant agents regarding online applications, time management by the syahbandar to make the sailing approval letter issuance faster and more effective and efficient.

Authors: Halim Arif Rahman
Published: October 2024

Surimi is Japanese, meaning crushed meat. To encourage fish consumption, products made from processed surimi are made more varied and interesting, such as fish dumplings. This research aimed to determine the differences in the sensory characteristics of surimi from different raw materials (swangi fish, kurisi fish, and kuniran fish). Apart from that, we also want to know the organoleptic and hedonic test results of fish dumplings made from different surimi raw materials. The surimi testing method includes an appearance test, folding test, and bite test on three different types of surimi (SU1 = kurisi fish, SU2 = swangi fish, SU3 = kuniran fish). Organoleptic and hedonic test methods for fish dumplings include appearance, smell, taste, and texture. The research results showed that there was a significant difference in the physical test of surimi (fold and bite test), while in the appearance test, there was no real difference. The surimi organoleptic test showed that there was no difference in smell and taste, while there were different results in appearance and texture parameters. The results of the hedonic test showed that panelists preferred sample SU1 on appearance and smell parameters, SU2 was preferred on taste parameters, and SU3 was superior on texture parameters.

Published: October 2024

Ocean currents are the movement of sea water masses in a certain direction caused by several factors, namely wind, tides and bathymetry. Hydrodynamic modeling aims to determine the speed and direction of ocean currents in the waters of Bakau Bay through a two-dimensional model. The current pattern of the north season to the east season is influenced by sea water masses with an average current speed ranging from 0.22-0.24 m/s, while the south season to West season currents with an average speed of 0.04-0.26 m/s, this shows the meeting of different water masses so that the speed and direction of the current results in random or rotating currents. From the calculations of the normality test and anova test, it is known that the field current and model simulation values are normally distributed and there is no significant difference in values in the two data, so based on the RMSE value, it shows that the difference in values between the model simulation results and direct data measurements is relatively small. This also shows that the ocean surface current model created is sufficient to describe actual conditions.

Prisoner education and prisoner’s multi?scalarity of identity negotiated from penitentiary discourse
Authors: Zhao Changyou , Ding Jianxin , Liu Yongliang
Published: October 2024

The growing interest in identity and language, coupled with increased interest in the relation between identity, language and education, has resulted in a rich amount of work that has informed education, identity and language. To keep abreast of the developments in identity research, the authors propose the research on prisoners’ identity changing from structuralism on identity as a set of generically inherent characteristics to social constructionist perspectives on identity as fluid and emerging in interaction. From the social constructionist perspective on identity, the prisoner’s multi-scalarity of identity is identified through the negotiation from penitentiary discourse indicating that the prisoners inhabit various identities in accordance with the discourses and discursive varieties that they are using, which requires us to alter the lens of seeing prisoners as having a single and stable identity of “Prisoner”. Prisoners’ fluid identity transformed from the legally fixed “prisoner” to the socially acceptable “people”, between which there is prisoners’ multi-scalarity of fluid identity, plays an important role in prisoners’ rehabilitation and socialisation. The successful identity transformation from “prisoner” to “people” means the efficient rehabilitating process of the prison for prisoners. The process of identity circulation has pedagogical implications for prisoner education.
Political self-praise in Clinton–Trump presidential debates

The speech act of political self-praise has received scant attention in East Asian contexts, unlike other speech acts. This study aims to explore the strategies of self-praise used by Hillary Clinton and Donald Trump. The 2016 US presidential debates were analysed quantitatively to examine if there are any differences in using self-praise strategies. This was followed by a qualitative analysis to explore how these strategies are linguistically realised. Three main self-praise strategies were used: unmodified explicit self-praise, modified explicit self-praise and indirect self-praise. Within the third category, the data revealed a new self-praise strategy, which we called “criticism-based self-praise”. Moreover, the findings highlighted differences in using self-praise strategies in American political discourse. While Trump employed unmodified explicit self-praise more than his opponent, Clinton used modified explicit self-praise strategies far more than Trump. Trump, however, adopted implicit self-praise strategies more than Clinton. Differences could be attributed to gender stereotypes as well as the candidates’ experience and personality. The study may help East Asian people better understand American political discourse, presidential debates in particular.
The Parmesan Pie (Part One)
Authors: Martellotti Anna
Published: October 2024

The article investigates the medieval European taste for pies, tarts and stuffed pastries which were often quite elaborate and sometimes filled with surprises. It looks at the Arabic influence which inherited the taste from the Babylonians although such pies were also known to the Romans and then turns to their later manifestation in Italy where they became known as Parmesan Pies.

ON IDENTIFICATION OF PARAMETERS OF A NONLINEAR CONSOLIDATION MODEL OF SANDY SOIL
Authors: Artamonova N. B. , Sheshenin S. V.
Published: October 2024

Previously, the authors of this article formulated a physically and geometrically nonlinear formulation of the problem of porous fluid-saturated medium deformation during fluid filtration (consolidation problem) in terms of the rate of solid phase displacement and the change in pore pressure in differential and variational forms. The developed consolidation model takes into account changes in the porosity and permeability of the medium during deformation. Deformation-type constitutive relations are used in the model. The developed consolidation model can be used to simulate non-stationary processes in the soil, for example, the formation of ruts and unevenness of dirt roads, as well as to calculate the uneven settlement of engineering structures. This work is devoted to the experimental determination of the deformation and strength properties of water-saturated sandy soils, which is the next stage in the consolidation process simulation. The results of the experimental determination of the bulk and shear properties of sandy soil using the ASIS automated complex (OOO NPP “Geotek”) are presented. The studies were carried out on three quartz sands of various grain sizes. To determine the volumetric moduli of dry and water-saturated sandy soils, compression tests were carried out under a continuously growing vertical load at a constant strain rate. The experiments were carried out for various strain rates in the range from 3·10–6 to 3·10–3 s–1. According to the experimental results, the bulk properties do not depend on the strain rate in the specified range. Deformation and strength shear characteristics of sandy soils were determined by the method of multiplanar shear, approximating a simple shear. The tests were carried out under a kinematically applied shear load with a given constant strain rate according to the scheme of consolidated-drained shear. The dependences of the deformation and strength properties of coarse and fine quartz sands on the shear strain rate in the range from 2·10–4 tо 4·10–3 s–1 were studied. Increasing, decreasing and nonmonotonic dependences of the internal friction angle on the shear strain rate were obtained for dry and water-saturated sands of various grain sizes. For water-saturated sands, the maximum spread in the values of the internal friction angle for different strain rates does not exceed 7 %. A technique has been developed for recalculating the obtained properties and experimental dependences into the parameters of the proposed sandy soil consolidation model.
MODELING OF HIGH-RATE HARDENING OF A POLYMER COMPOSITE MATERIAL UNDER LOADING ALONG THE REINFORCEMENT DIRECTION

Published: October 2024

Modeling the high-rate deformation of composite structures is of great interest in the industry. Moreover, some processes such as accidents, explosions and possible impact issues require analysis of composite materials at significantly high deformation rates. The paper considers the possibility of developing a model of deformation of a composite material based on a polymer matrix and carbon fiber taking into account high-rate hardening. A feature of the study is the development of a model that takes into account a wide range of deformation rates from static to several thousand reverse seconds. Thus, tests were carried out with special equipment and samples that allow us to obtain data with such high loading speeds. The model is based on an approach considering the use of damage parameters, the so-called class of models with progressive degradation. The main innovative part of the chosen model is the formalization of the rate of deformation on the material through the damage parameter, that is, the rate of change in damage values is considered. This approach makes it possible to make constitutive relations based only on the damage parameters, which modify the stiffness and strength characteristics of composites, which greatly simplifies the modeling and analysis of material deformation.
Large Deflections, Loss of Stability and Over-Critical Behavior of Sloping Panels and Arches of Variable Thickness on an Elastic Base
Authors: Kayumov R. A
Published: October 2024

The problem of large deflections of a flat arch in its plane (or an infinitely long panel) loaded with transverse loads is considered. A variational approach has been applied to solve it. The resolving nonlinear equations are reduced to finding the deflection and longitudinal force, which is considered constant along the length of the arch due to its flatness. An approximate solution method is proposed by decomposing the displacements into a Fourier series. The peculiarity of the approach used is that in order to pass the limit points, it is not necessary to use special algorithms such as the continuation method by parameter. It also allows you to trace the process of supercritical deformation of the arch. The proposed approach allows us to consider problems for arches of variable thicknesses, located on elastic supports, on an elastic base with a variable bed coefficient and various loads. Therefore, it is also convenient in problems of finding, for example, the optimal thickness distribution under restrictions on critical loads, on rigidity stiffness and on maximum compression or tension stresses. The results of numerical calculations are presented. The convergence is studied of the solution depending on the number of terms of the series, into which the desired deflection decomposes. A good agreement with the known analytical results is obtained earlier by solving the equilibrium equations of the arch element and panel in the case of simple types of loading. At the same time, even in more complex cases of loading and supercritical bending of an arch without an elastic base, the results are obtained when holding three, four and five members of the Fourier series, the maximum deflections and critical loads differed by no more than 2.5%. On the basis of numerical experiments, the features of the arch behavior caused by the rearrangement of geometry during loading are revealed. The processes of stability loss of the arch and its supercritical behavior are investigated. The effect of symmetric deformation in the case of kinematic loading is found, namely, it is revealed that at a certain value of the concentrated force, an infinite number of equilibrium forms are possible. Arches on an elastic base, as well as with variable thickness are considered (the results are presented in the form of load–displacement diagrams and in the form of pictures of deformed arch shapes). An interesting effect has been revealed based on numerical experiments. It turned out that the increase in thickness when moving away from the supports does not change the nature of the load–displacement diagram, i.e., with some load, a slap occurs. On the contrary, a decrease in thickness when moving away from the supports leads to a flattening of the diagram, and after a certain thickness value in the center, its further decrease leads to the fact that the arch does not occur.
DEFORMATION OF A THIN FILM AFTER CONTACT LOSS WITH A CYLINDRICAL BASE, WITH ACCOUNTING FOR THE INFLUENCE OF ITS CURVATURE, COMPLIANCE, AND ACTION OF TRANSVERSE FORCES; DELAMINATION LOCATED IN THE CIRCUMFERENTIAL DIRECTION
Authors: Gandilyan D. V
Published: October 2024

Delamination of a coating from a cylindrical substrate under compressive stresses is considered. The solution of the problem was obtained within the theory of cylindrical shells. The Mushtari-Donnell-Vlasov equations were used as the equilibrium equations, and the conditions of the generalized elastic clamped type were used as the boundary conditions. Expressions are obtained for the coating displacement components and the energy release rate during delamination along the rectilinear and curvilinear delamination boundaries. The profiles of the exfoliated section of the coating were obtained. The role of the substrate compliance and its curvature on the values of the energy release rate and the angle of rotation at the clamping point, as well as in the change in the shape of the coating profile, is revealed. It is shown that with an increase in the compliance of the substrate, as well as the value of (positive) curvature, the value of the energy release rate and the value of the normal component of the displacement of the coating increase significantly. It has been found that at sufficiently large values of the substrate curvature, a corrugation effect occurs in the profile of the delaminated section of the coating, which results in the local extrema in the graph of the dependence of the energy release rate on the delamination length. This effect was not observed in the delamination located in the longitudinal direction [1]. It is also shown that for sufficiently compliant substrates there is a certain critical delamination width, for which it becomes energetically more favorable for delamination to develop in the circumferential direction than in the axial one. As the positive curvature and compliance of the substrate increase, the value of the critical width decreases. An alternative criterion for the critical delamination width is also considered, which consists in studying the value of the angle of rotation at the embedding point, which corresponds to the overlap of the coating and substrate surfaces at an angle value of zero.
