The effect of the various porous layers on thermomechanical buckling of FGM sandwich plates

Abstract

This study focuses on the thermal buckling behavior of sandwich porous plates made up of metal-ceramic functionally graded material (FGM) components using a new sinusoidal high order shear theory. The sandwich plate consists of a core plate made of either pure metal or pure ceramic, with face layers composed of a functional gradient of metal and ceramic constituents. This study examined the porosity and four porosity distribution functions in plates with FGM face layers and nonlinear temperature increase and material grading index of the face layers on the thermal buckling loads of sandwich plates.
