The main aim of this work is to use a finite element method (FEM) based on Shi’s third-order shear deformation plate theory (TSDT) to study the dynamic response of sandwich plates subjected to consecutive blast loading. The sandwich plate has an auxetic honeycomb core and two different functionally graded materials (FGMs) skin layers (so-called h-FGS plates).

In this paper, free vibration of bidirectional functionally graded sandwich (BFGSW) beams is studied by using a finite element formulation. The beams made from three distinct materials are composed of three layers, a homogeneous core and two bidirectional FGM face layers with material properties varying in both the thickness and longitudinal directions by power gradation laws.

The paper aims at introducing an analysis of thin-walled functionally graded sandwich beams for general nonuniform quadrilateral cross-sections. Generally, the materials are assumed to be graded through the thickness following a predefined shape while Poisson’s ratio kept as a constant due to its less domination. The crosssection linearly varies from one end to another end of the beam.
