Nonlinear dynamic analisys of reservoir shell with modelled shape imperfections
Authors: Lukianchenko Olha , Gerashchenko Oleh , Paliy Oksana 
Published: February 2023

The nonlinear dynamic analysis of imperfect reservoir shell with a variable thickness of wall under pressure was executed. The finite-element model of reservoir in the form of a cylindrical shell in the software NASTRAN was built. The shell wall in the form of the three-cornered finite-element net was presented. Shape imperfection as a lower buckling form of perfect shell (Buckling) was modelled. Value of amplitude of imperfection was set proportionally to a minimum thickness of shell wall. The limits on the radial and tangential displacements of top edge nodes were entered, the nodes of lower edge were fastened. Excitation as external pressure, which linearly depended on time and uniform distributed on all shell elements was presented. The modal analysis of shell with modelled shape imperfections by using computational procedure of task on natural vibrations (Normal Modes) by the Lanczos method was executed. The nonlinear dynamic analysis (Nonlinear Direct Transient) of imperfect reservoir shell under pressure by N’yumark method was executed. Influence of amplitude of modelled imperfection on the shell stress-strain for different time intervals of excitation, the conditionally critical values of dynamic loading and corresponding of shell deformation forms were investigated.
It was discovered that a modelled shell shape imperfection as a lower buckling form of perfect shell under static pressure in the dynamic analysis of shell under the same type of the loading was effeсtive. Influence of modelled shape imperfections amplitude on the stress-strain state of shell for different time interval of excitation, the conditionally critical values of dynamic loading and appropriate forms of shell deformation was considerable. Presented imperfection model in the modal analysis of shell was not effective. The increase of amplitude of shell imperfection led to insignificant decrease of natural frequencies and amplitudes of appropriate natural forms with the same amount of the semiwaves in the circular direction. In our opinion presented model of shell shape imperfection can be effective in the modal analysis of shell with the stress-strain state from the previous action of static pressure and for the estimation of design reliability of reservoir shell in the case of the dynamic loadings using the Bolotin probabilistic approach.
Influence of material functional heterogeneity on non-stationar oscillations of piezoceramic bodies
Authors: Hryhorieva Ludmila , Yanchevskyi Ihor 
Published: February 2023

The influence of material functional heterogeneity on mechanical oscillations of piezoelement under non-stationary electrical loading is investigated. Within the assumption of functional distribution of material characteristics by thickness of the piezoelectric element, which corresponds to the physical properties of the body, a unified system of solving equations was obtained to describe the thickness fluctuations of piezoelectric plates, cylinders, and balls. For controllingof accuracy, the calculation is carried out using an explicit and implicit difference scheme.
Unsteady oscillations of a flat piezoceramic layer, cylinder, and sphere are investigated with a parabolic distribution of all material characteristics along the thickness of the element. It is assumed that the average value of the function along the thickness is equal to the tabular value of the material characteristic, and the value on electrodes is proportional to the area of electrodes. At such conditions, we obtained a decrease in the speed of disturbances propagation and a slight change in the amplitude associated with the curvature of the element. The increase in amplitude reaches 3% for balls. It should be noted that at given load oscillations occur in the compressed zone without entering the undeformed state. The considered cylinder and ball have a rather large curvature, for bodies with a smaller curvature the influence of the described effect will be smaller. The additional analysis indicates that the shape of the distribution curve under described above conditions also has little effect on the results.
It was established that the effect of functional heterogeneity within the same material has little effect on the oscillations of the piezoelement, that is, it is really possible to average the material characteristics by thickness at calculating, since the deviation between the results is within acceptable limits (up to 2.5%). Also, an important result is the confirmation of the assumption that for curved bodies such as cylinder and sphere, the material characteristics can be considered constant on thickness, regardless of the curvature of the body.
The proposed technique can be applied for studyingof the vibrations of different geometries bodies with significantly heterogeneous functional material or what are combined from several materials with a gradient transition between them.
Monitoring of the elements stability of building constructions by means of example of vertical elastic rod of high flexibility
Authors: Isaev Oleksandr , Annenkov Andrii , Demianenko Roman , Chulanov Petro 
Published: February 2023

The article is related to the field of geodetic and engineering construction monitoring of building structures in the form of rod systems. It investigates the measurement accuracy of the compression deformation of the rod. As an example, there is considered a vertical rectilinear rod of high flexibility, loaded with a longitudinal axial force. Experience demonstrates that the rod, under the influence of an axial compressive load not exceeding the permissible design values, retains its original form of equilibrium and stability. At the same time, it works in the field of elastic compression deformations. As the load increases to its critical values, there occurs a particular state of the element when the form of equilibrium becomes unstable, and at any moment, it can turn from a straight line into a curvilinear one with a slight external influence or as a result of position errors. This is accompanied by large displacements and permanent deformations. The importance of monitoring is noted when a building structure with similar constructions, for example, is situated in the area of development of negative natural and anthropogenic processes. As a result, the load on some elements may increase to critical values due to uneven horizontal and vertical displacement and inclination of the structure, including vibrations, etc. Attention is focused on the fact that the complex of engineering and technical measurements should show, with the necessary completeness, reliability and accuracy of the value, the nature and dynamics of changes in the external load on the elements of the building structure, changes in internal forces and stresses in them, the development of deformations (changes in the size and shape of equilibrium). There is explained the accuracy with which it is necessary to measure the displacement of the rod end during the deformation. There was derived the dependence with the help of which it is possible to see the root-mean-square error of the displacement measuring that depends on the choice of the maximum stress deviation in the sections of the rod made of a certain material. There is laid out the calculation of the maximum stress deviation based on the stability and flexibility of the rod.

Published: February 2023

The impact of the elasticity of the polymer filler of a three-layer cylindrical structure of normal elliptical cross-section on its stress-strain state under internal impulse loading was studied. Determined values and distribution of normal deflections and stresses in sections S1 and S2. The finite-element method of calculating the stress-strain state (SSS) of such a structure by the software-calculation complex Fimap with NX Nastran was applied. Conclusions were made regarding the sufficient expediency of considering the elasticity of the filler when optimizing the design of such structures.
Increasing the elasticity of the polymer filler increases the strength and monolithicity of the layered structure. The use of this method ensures efficiency and is appropriate when the ratio of elasticity of the materials of the layers and filler is Е1.3 /Еt ≤50.
APPLICATION OF GIS TECHNOLOGIES FOR THE FORMATION OF THE GEOSPATIAL DATABASE OF
GASTRONOMY TOURISM OF UKRAINE

Published: February 2023

Gastronomic tourism as a rapidly developing type of tourism, and being a complex
system, requires quality management. The use of geoinformation systems and technologies
can contribute to the formation of management decisions regarding the effective
development of this type of tourism.
The article examines the essence of gastronomic tourism and the use of GIS technologies
to form a geospatial database. The cartographic method of researching the presented
phenomenon is applied and the possible cartometric operations in the work of the tourist
GIS of the gastronomic direction are described. In this study we have developed a
technological scheme for creating gastronomic tourism routes using GIS technologies. We
present the conceptual and structural-logical model of the geospatial database of
gastronomic tourism developed by us. A geospatial data base of gastronomic tourism for
Odesa region, which is distinguished by its gastronomic colour and is in great demand
among travelers, has been created and visualized. Local specialized objects of
gastronomic tourism of this region were found and the database tables were filled with
reliable attributive data. The locations of the concentration of gastronomic objects in
Odesa are visualized with the help of a heatmap, and typical requests of users regarding
the identification of objects of interest when designing gastronomic routes are given.
The city of Odessa was identified as the most attractive place for gastronomic tourism
in Odesa region, as it is the one around which the vast majority of various objects of
gastronomic tourism is concentrated. Various gastronomic routes through Odesa region and
Odesa with buffer zones along them have been designed, which can be of interest to both
tourists and tour operators when creating gastro tours. The proposed methodology can be
used for a similar analysis of other regions and, in our opinion, will contribute to
increasing the number of tourist trips to the region and the development of gastronomic
tourism in Ukraine as a whole.

Published: February 2023

Sheep breeding is a branch of animal husbandry that is unique in terms of the variety and specificity of products. Sheep can utilize feed resources that are almost inaccessible to other types of farm animals. One of the factors in increasing the efficiency of sheep breeding is ensuring the well-being of farms concerning invasive diseases, particularly trichurosis. Successful control of trichurosis in sheep farms is the most effective for monitoring and forecasting the development of the epizootic situation depending on the climate-geographical zone. The work aimed to monitor the epizootic situation regarding sheep trichurosis in the Poltava region. According to the analysis of the statistical data of the reporting documentation of the Main Department of the State Production and Consumer Service in the Poltava region for 2018–2022, it was established that the share of helminthiasis among diseases of infectious etiology of sheep reaches 99.6 %. At the same time, among helminthiasis, nematodes have the highest specific weight – 69.0 %, and trematodes were less common – 31.0 %. Strongyloidiasis (68.05 %) was diagnosed most frequently among helminth infections during the studied period. A smaller percentage was strongylidosis of digestive organs (17.16 %) and trichurosis (11.24 %). Dictyocaulosis was rarely diagnosed among livestock (3.55 %). The average extent of trichurosis infestation of sheep during the investigated period in the territory of the Poltava region was 7.51 %, ranging from 5.83 to 9.26 %. Indicators of the extent of trichurosis invasion ranged from 5.45 to 33.33 % by area. According to the results of coproovoscopy, the highest values of sheep infestation with Trichuris were found in the farms of Karliv and Mashiv regions – 33.33 and 20.0 %, respectively. Less often, trichurosis was diagnosed in sheep farms of Dykanskyi (8.0 %), Reshetylivskyi (6.67 %), and Kotelevskyi (5.45 %) districts. The obtained data from monitoring studies prove the relevance of the further and more in-depth analysis of the spread of trichurosis infestation among sheep in the territory of the Poltava region, taking into account the age and seasonal dynamics of the disease, as well as the peculiarities of its course as part of mixed infestations.

Contingent Colonialities

Published: February 2023

This work in progress report presents the bilingual mapping project “Decolonizing The Narrative of Cabeza de Vaca/Descolonizar La relación de Cabeza de Vaca,” an interdisciplinary undergraduate, graduate, and faculty digital humanities collaboration that aims to educate users about the impacts of Spanish colonization and its ramifications on the creation and evolution of latinidades in the Americas by (1) recovering the history of that colonization within Latin America as well as what became the United States, (2) analyzing how and by whom that history has been narrated, and (2) considering what impact those narratives have on society today.
Written in Spanish, La relación precedes English-language accounts that describe what is now the United States, providing necessary historical context for the centuries-long development of transborder latinidades throughout the hemisphere. At the same time, the fact that La relación was not written in English does not mean the text is not Eurocentric. On the contrary, fully apprehending La relación and its impact requires a decolonial approach that decenters Cabeza de Vaca and his limited perspective. By visualizing this Spanish colonial narrative, this project provides not just a window into what became the pre-Anglophone Southern and Southwestern United States, but also brings into sharp relief the complexities of the overlapping colonialities these lands have experienced, as well as the way the interplay among those colonialities has shaped U.S. Latinx communities and their relationship to hemispheric latinidades.

Published: February 2023

Despite recent experimental and clinical progress in the treatment of tibial and fibular fractures, in clinical practice rates of delayed bone healing and non-union remain high. The aim of this study was to simulate and compare different mechanical conditions after lower leg fractures to assess the effects of postoperative motion, weight-bearing restrictions and fibular mechanics on the strain distribution and the clinical course. Based on the computed tomography (CT) data set of a real clinical case with a distal diaphyseal tibial fracture, a proximal and a distal fibular fracture, finite element simulations were run. Early postoperative motion data, recorded via an inertial measuring unit system and pressure insoles were recorded and processed to study strain. The simulations were used to compute interfragmentary strain and the von Mises stress distribution of the intramedullary nail for different treatments of the fibula, as well as several walking velocities (1.0 km/h; 1.5 km/h; 2.0 km/h) and levels of weight-bearing restriction. The simulation of the real treatment was compared to the clinical course. The results show that a high postoperative walking speed was associated with higher loads in the fracture zone. In addition, a larger number of areas in the fracture gap with forces that exceeded beneficial mechanical properties longer was observed. Moreover, the simulations showed that surgical treatment of the distal fibular fracture had an impact on the healing course, whereas the proximal fibular fracture barely mattered. Weight-bearing restrictions were beneficial in reducing excessive mechanical conditions, while it is known that it is difficult for patients to adhere to partial weight-bearing recommendations. In conclusion, it is likely that motion, weight bearing and fibular mechanics influence the biomechanical milieu in the fracture gap. Simulations may improve decisions on the choice and location of surgical implants, as well as give recommendations for loading in the postoperative course of the individual patient.
