Published: November 2024

O objectivo deste trabalho é o desenvolvimento de modelos numéricos que permitam prevercom rigor o comportamento mecânico de juntas coladas. Os modelos baseiamse no uso de elementos finitos de interface, para problemas tridimensionais, que são colocados entre os substratos e o adesivo. Numa primeira fase são determinados os campos de tensões com o intuito de definir zonas críticas percursoras da iniciação do dano. Posteriormente é também incluído um modelo de dano progressivo que permite simular a iniciação e a propagação do dano. Foram realizados ensaios experimentais em juntas de alumínio/epóxido de sobreposição simples. A simulação numérica para a previsão da resistência da junta, foi feita tendo por base análises linear elástica e elastoplástica, considerando três comprimentos de sobreposição. A carga de rotura prevista na análise elastoplástica apresentou boa concordância com os resultados experimentais.

Published: November 2024

Uma das etapas mais críticas do ciclo de vida de um produto, é o seu projeto, por ser um processo intensivo que trata de uma grande e diversificada quantidade de informações e conhecimentos. Para que as decisões tomadas nesta etapa sejam as melhores possíveis, é necessário que os projetistas disponham, de informações e conhecimentos sobre o produto em si, bem como aquelas relacionadas com seu ciclo de vida. Um caso onde essas características podem ser evidenciadas é no desenvolvimento de materiais de atrito para sistemas de freios. Neste caso o projeto está bastante direcionado à formulação da matériaprima e ao seu processo de fabricação. Desta forma, as características finais do produto material de atrito dependerão não somente da formulação, que é um processo empírico, como também dos parâmetros utilizados para o processo de fabricação. Este trabalho aborda aspectos relacionados com a identificação, captura e compartilhamento de informações e conhecimentos envolvidos no projeto do material de atrito utilizado em sistemas de freio. Uma abordagem baseada em modelos de informações é utilizada como forma de possibilitar uma visão integrada do produto, além de apoiar a reutilização de informações e conhecimentos gerados em projetos anteriores. Dois modelos de informações são propostos, a saber, o modelo de produto que contempla informações sobre um produto em específico e o modelo de conhecimento do projeto que captura o histórico das informações e conhecimentos gerados ao longo do projeto do material de atrito. A representação destes modelos é baseada na tecnologia orientada a objetos e a recuperação das informações em uma abordagem de Raciocínio Baseado em Casos.

Validação da medição de deformações por correlação digital de imagem em compósitos laminados de matriz polimérica
Authors: Chousal J.A.G. , De Moura M.F.S.F 
Published: November 2024

Neste artigo é apresentado um procedimento de simples implementação que pode ser usado para medir deslocamentos no plano de imagem de um objeto. Esta medida pode ter uma precisão de medição variável, dependente da textura e do sistema óptico formador de imagem. O método é baseado na correlação espacial realizada sobre duas imagens, uma antes e outra após carregamento. O recurso à transformada de Fourier permite reduzir o tempo de processamento e representa a etapa principal do processamento digital de imagem necessário à deter minação do deslocamento sofrido pela área da imagem. Para verificar a capacidade de medi ção do procedimento foram efectuadas medições simultâneas com um ensaio de tracção de placas de um material compósito de matriz polimérica. Posteriormente fezse a comparação para algumas das propriedades do material usando o procedimento habitual do ensaio de tracção e a medição da deformação por correlação de imagem, tendose obtido uma boa concordância entre os dois procedimentos.
Modelação numérica de reparações por sobreposição simples e dupla em materiais compósitos
Authors: Campilho R. D. S. G. , De Moura M. F. S. F. 
Published: November 2024

A utilização de materiais compósitos reforçados com fibras tem vindo a aumentar na indústria, no-meadamente a aeroespacial, devido às suas excelentes características de resistência e rigidez específicas. A presentam no entanto uma susceptibilidade elevada ao impacto, nomeadamente o impacto de baixa velocidade, provocado por exemplo por um embate acidental de uma ferramenta numa estrutura em compósito ou um em- bate de uma ave numa asa de um avião, entre outras situações. Tornase assim fundamental tentar prever uma forma de reparação destas mesmas estruturas, não só por questões económicas, como também ambientais, uma vez que este tipo de materiais é dificilmente reciclável. O presente trabalho é dedicado ao estudo numérico das componentes de tensões e resistência residual à tracção de reparações efectuadas em materiais compósitos por sobreposição simples e dupla, utilizando o código comercial de elementos finitos ABAQUS®. É estudado o efeito de algumas alterações geométricas nas distribuições de tensões e na resistência da reparação. O estudo e- fectuado permite comprovar que podem ser obtidos bons rendimentos após reparação de uma placa danificada, dependendo da geometria, sequência de empilhamento da placa a reparar e espessura da mesma.

Authors: Voronin Boris F. , Álvarez Sánchez Jesús A. 
Published: November 2024

En el artículo se propone un nuevo método analítico para el análisis cinemático de mecanismos articulados planos, que consiste en la combinación de los métodos del álgebra vectorial y del método de L.V. Assur, el cual se basa en la construcción de los mecanismos articulados a partir de grupos estructurales y de mecanismos de primera clase. Se muestra el modo de obtención de las ecuaciones para el análisis cinemático de los mecanismos de primera clase y de los grupos estructurales de segunda clase de tercera variedad. El enfoque propuesto simplifica mucho el análisis de mecanismos de cualquier grado de la complejidad ya que esto no requiere la formulación de las ecuaciones para el mecanismo completo. El mecanismo se presenta compuesto de bloques que tienen en su estructura mecanismos de primera clase,grupos estructurales y el conjunto de ecuaciones que los acompañan. Para mostrar elmétodoétodo se toman, como ejemplo, mecanismos planos de cuatro eslabones. El método está dirigido a los profesores que imparten clases de Teoría de Mecanismos y Máquinas, a los ingenieros diseñadores de sistemas mecánicos y a los ingenieros que desarrollan SOFTWARE.

Published: November 2024

Purpose
The study investigates the role of the dynamic capabilities of learning, integration, and re-configuration on the quality of decision-making mediated by data-driven insights. It particularly examines how these dynamic capabilities individually contribute to offering efficient and effective decision-making in the hospitality sector.
Design/methodology/approach
This study employs a quantitative research approach harnessed through surveys and the application of partial least square structural equation modelling using SMART PLS 4. The hospitality sector being a highly competitive industry was selected for data collection.
Findings
The findings reveal that learning and reconfiguration capabilities have a significant positive individual impact on generating data-driven insights hence improving the effectiveness and efficiency of decision-making. Contrarily, the integration capabilities standalone did not influence in pointing out the statistical significance of the relationship with data-driven insight or decision-making quality, an indication that integration has to be combined with other dynamic capabilities for it to be effective.
Originality/Value
This study adds novelty to the literature by examining the individual influences of dynamic capabilities—learning, integration, and reconfiguration on data-driven insights and decision-making quality. Unlike previous studies that have generally explored bundles of capabilities, this study isolates each to answer the more nuanced question of how organizations can, in a strategic manner, invest in certain dynamic capabilities that can improve decision-making.

A poverty-free region is one of the seventeen Sustainable Development Goals (SDGs) targets approved by the United Nations in 2015. It aims to end extreme poverty for all people earning less than $1.25 per day and promote inclusive and equitable development. Per capita, income is one of the critical indicators of human resource development and the economy. This research aims to identify economic growth in the context of per capita income and to monitor and evaluate the achievement of the SDGs Without Poverty in the Sampang district. This qualitative study uses a descriptive analysis approach, with data collection methods including observation, documentation, and library research. The research focuses on the achievement of the SDGs Without Poverty indicator, which consists of five key indicators: (i) Percentage of the population living below the national poverty line; (ii) Implementation of the social protection system; (iii) Guarantee of economic resources and fundamental service rights (health, housing, lighting); (iv) Strengthening and development of disaster-resilient areas, and (v) Government policies and proportions in poverty alleviation, as well as several sub-indicators set by the National Development Planning Agency. The study results showed that the increase in per capita income had a negative but insignificant correlation with the poverty rate. However, per capita income positively impacts realizing the SDGs Without Poverty. It has achieved the goal of ending extreme poverty for all people with an income of less than $1.25 per day.

Published: November 2024

Background: Men with extensive chronic liver disease usually have low levels of testosterone in the serum. This study looked at the relationship between hypogonadism and low serum testosterone levels in patients with chronic liver disease. Methods: This retrospective study was conducted at Central Park Teaching Hospital, Lahore from Jan 2022 to Jan 2024, on patients between 5 to 60 years of age. After approval from ERB and permission from the authorities, records were retrieved. Two hundred records of men with hepatic cirrhosis and verified hypogonadism were divided into alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD), while records of 150 men as control group were include in the study. Patients’ data for ‘Sex Hormone Binding Globulin (SHBG)’ and ‘total testosterone’ were collected and entered into MS Excel file. Using SPSS-22 independent Student’s t-test was applied for statistical analysis. Results: No statistically significant variations were observed (p=0.101) in the means of SHBG across two groups but there was a statistically significant (p<0.05) variation in blood serum testosterone levels between age groups. Conclusion: Hypogonadism and low levels of testosterone are strongly linked to male patients with cirrhotic liver conditions, particularly in those with ALD, while no significant impact of SHBG was found between the two groups. Significant differences were observed between patients with ALD and NAFLD in terms of testosterone levels.
