“…Concluding remarks are element 189, which is the best element to perform a beam analysis rather than a 188 element and other solid elements 285. Vanam B. C. L et al [30] analyze a static analysis of a rectangular isotropic plate under different boundary conditions and load applications by finite element analysis. The results of the FEA and ANSYS (Kirchhoff plate theory) have been compared to exact solutions and showed that closed matching.…”

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.

An analysis of the mechanical properties of plasma enhanced chemical vapor (PECVD) silicon nitrides is presented, using micro fabricated silicon nitride membranes under point load deflection. The membranes are made of PECVD silicon-rich nitride and low stress nitride films. The mechanical performance of the bended membranes is examined both with analytical models and finite element simulation in order to extract the elastic modulus and residual stress values. The elastic modulus of low stress silicon nitride is calculated using stress free analytical models, while for silicon-rich silicon nitride and annealed low stress silicon nitride it is estimated with a pre-stressed model of point-load deflection. The effect of annealing both in nitrogen and hydrogen atmosphere is evaluated in terms of residual stress, refractive index and thickness variation. It is demonstrated that a hydrogen rich annealing atmosphere induces very little change in low stress silicon nitride. Nitrogen annealing effects are measured and shown to be much higher in silicon-rich nitride than in low stress silicon nitride. An estimate of PECVD silicon-rich nitride elastic modulus is obtained in the range between 240–320 GPa for deposited samples and 390 GPa for samples annealed in nitrogen atmosphere. PECVD low stress silicon nitride elastic modulus is estimated to be 88 GPa as deposited and 320 GPa after nitrogen annealing.

“…Actualmente esta técnica se ha utilizado en una amplia variedad de problemas, y tiene distintos enfoques para sus soluciones. (Croninl 2001;Moreno et al, 2007;Vanam et al, 2012) Roylance (2001), Pallares y Rodríguez (2009), Vélez et al (2009), exponen la importancia del uso de herramientas de simulación como el programa comercial de elementos finitos ANSYS como alternativa viable para la solución de problemas de ingeniería, ya que constituye un ejercicio de interiorización teórica y práctica de fenómenos naturales o procesos que de otra manera sería complejo explicar desde el punto de vista cuantitativo y aun cualitativo. Un software de elementos finitos como ANSYS contienen herramientas que permiten el modelado y la simulación de un gran número de fenómenos, estructuras y materiales, para lo cual divide su operación en etapas o módulos, donde generalmente se definen aspectos tales como geometría del modelo, tipos de elementos en los que se dividirá, asignación de propiedades de los materiales y generación de la malla para definir los nodos y uniones entre elementos.…”

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.
