Abstract

The main aim of this paper is to analyze the nonlinear electro-thermo-mechanical dynamic buckling and vibration of third-order shear deformable circular plates and spherical caps with functionally graded graphene platelet reinforced composite (FG-GPLRC) coatings, piezoelectric layers, and porous core. The circular plates and spherical caps are assumed to be rested on the Pasternak visco-elastic foundation, and subjected to dynamic external pressure in the thermal environment. The total potential energy expression of structures is established using the Lagrange function. The Euler-Lagrange equations and Rayleigh dispassion functions are applied to obtain the motion equation of structures. This motion equation can be solved using the Runge-Kutta method to obtain the dynamic responses of circular plates and spherical caps. Significant discussions of the different effects of graphene distribution, graphene volume fraction, piezoelectric layers, porous core, and foundation parameters are presented through the investigated examples.
