“…32 Nº 6 -2021 llamada borde o límite. La distancia entre las caras planas se llama espesor el cual es pequeño en comparación con otras dimensiones características de la placa como longitud y ancho y se mide en una dirección normal al plano medio, para fines de cálculos técnicos como los presentados en este artículo se define una placa plana delgada como aquella en la cual la relación de su espesor a la longitud de su dimensión más pequeña debe ser inferior a 1/20 (Manjunath et al, 2014;Yuwaraj y Param, 2016;Hassan, 2019).…”

En este estudio se desarrolla y valida un modelo para simular numéricamente los esfuerzos normales y cortantes inducidos sobre las caras superior e inferior de una placa plana rectangular e isotrópica. La placa está apoyada en sus cuatro bordes y la presión es uniformemente distribuida sobre toda su área. Las soluciones analíticas se hallaron por medio de la ecuación general de placas utilizando el método series dobles de Fourier. Las soluciones numéricas se obtuvieron por el método de elementos finitos (software ANSYS 19.1). La validación del modelo se realiza comparando estadísticamente las soluciones analíticas y numéricas de los esfuerzos inducidos en un experimento clásico con tres niveles de presión. Los resultados muestran que no hay diferencia estadística significativa entre los dos tipos de soluciones. Se concluye que el modelo de simulación numérica es válido.

“…The incorporation of multiple holes causes buckling factor to decrease and stress concentration zones to decrease. Ahmed Hassan et al [53] have done a buckling analysis of both isotropic and functionally graded rectangular plates with various boundary conditions and meshing of plate structure using ANSYS. The results obtained from ANSYS are compared to analytical solutions based on different plate theories and the theory of 3D elasticity.…”

A composite material is generally a combination of materials differing in composition or form on a macro scale for the purposes of attaining specific characteristics and properties. The developments in the field of composite materials have granted significant weight reduction in structural design. When compared to metallic materials, composites offer many advantages, especially high strength, stiffness to weight ratio, excellent fatigue properties, and corrosion resistance. Plates, curved panels, the cylindrical shell-shaped forms of models are being broadly used in many structural packages of engineering structure. For design the structure, it is important to know the behaviour of these under static, free vibration, buckling condition. The present paper aims to review the literature on static, free vibration, and buckling analysis of composite flat panel, curved panel, and cylindrical shell. Further, the testing procedure of laminate, design guidelines of laminates and cost estimations with mechanical properties comparison of laminate with metal, CLT (classical lamination theory) basis including thermal and moisture expansion for stiffness evaluation are also summarised in this paper.

“…This value is the so-called critical force. We are dealing here with the phenomenon of buckling (Hassan and Kurgan [34], Onyeka et al [35]). The phenomenon of plate buckling can be classified as elastic and inelastic buckling.…”

The issue of large deflections of textiles occurs primarily when analyzing the “drape” of curtains, tablecloths and other flat textile products. The correct drape is particularly important from an aesthetic point of view. Additionally, there is a problem with the stability of the folds created during the drape process. The analysis of this problem is difficult due to the occurrence of large deflections and non-linear properties of the material. In this article, a selected fragment of the above-mentioned issue was tested, relating only to the stability of the fold formed under given loading conditions. A typical example is a fabric resting on a flat surface and loaded with compressive forces. The presented considerations lead to obtaining the deflection curve for a given self-weight and compressive force. Additionally, the obtained shape was tested for stability. Two shape parameters used in the analysis can be applied for the simulation of different shapes of the deflection curve. The analysis has been made using the energy method relating to the total potential energy of the object. The obtained results may be used in algorithms and simulation programs for fabric folding, buckling and for another applications in the area of textile mechanics.
