DYNAMIC RESPONSE ANALYSIS OF h-FGS PLATES SUBJECTED TO CONSECUTIVE BLAST LOADING

Abstract

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). The honeycomb core helps significantly reduce the weight of the sandwich structures as well as enhance vibration absorption. The governing equation is derived from Hamilton's principle. After verifying the present approach, the effect of input parameters on the dynamic response of h-FGS plates is carried out in detail. The obtained results are expected to be useful for calculating and designing h-FGS plates in practical engineering.
