Plate-based lattices are predicted to reach theoretical Hashin–Shtrikman and Suquet upper bounds on stiffness strength. However, simultaneously attaining high energy absorption in these plate-lattices still remains elusive, which is critical for many structural applications such as shock wave absorber protective devices. In this work, we present bi-material isotropic cubic + octet sandwich comp...

This work presents a detailed investigation of the effect auxeticity synergised with pyro-coupling behaviour multiphase magneto-electro-elastic (M-MEE) composites using finite element (FE) framework. The nonlinear deflection and bending problems sandwich plates auxetic core M-MEE skins subjected to multi-physics load (electric, magnetic thermal) are probed. plate kinematics is governed by Reddy...

The present work deals with evaluating the nonlinear deflections of smart sandwich plate agglomerated Carbon Nanotubes (CNTs) porous core and piezo-magneto-electric (PME) facings, using a novel finite element method (FEM) – artificial neural network (ANN) approach. For first time, an ANN-based computational tool that integrates effects agglomeration CNTs, porosity pyro-coupling PME materials is...

In this paper, an approach to aeronautical structural design based on reliability analysis is presented. In this way, the concept of level of safety is discussed and methods of its calculation using statistical data are described. Based on the concept of level of safety, a design procedure is proposed. In order to validate this design procedure, two design cases are studied. In the first case s...

An accurate solution procedure based on the three-dimensional elasticity theory for the free vibration analysis of Functionally Graded Sandwich (FGS) plates is presented. Since no assumptions on stresses and displacements have been employed, it can be applied to the free vibration analysis of plates with arbitrary thickness. The two-constituent FGS plate consists of ceramic and metal graded thr...

A novel refined arctangent exponential shear deformation theory (RAESDT) is presented for analysis the mechanical behavior of both isotropic and sandwich FGM plates. Material properties are set to be at each point varied across thickness direction obeying a power-law distribution volume fraction gradation with respect core or skins plate. Unlike high-order plate theories based on five more vari...
