摘要

本文的主要目的是分析带有功能分级石墨烯平板增强复合材料（FG-GPLRC）涂层、压电层和多孔核心的三阶剪切变形圆板和球帽的非线性电热力学动态屈曲和振动。假定圆板和球帽位于帕斯捷尔纳克粘弹性基础上，并在热环境中受到动态外压。利用拉格朗日函数建立了结构的总势能表达式。应用欧拉-拉格朗日方程和瑞利分散函数得到结构的运动方程。使用 Runge-Kutta 方法可以求解该运动方程，从而获得圆板和球帽的动态响应。通过所研究的实例，对石墨烯分布、石墨烯体积分数、压电层、多孔核心和地基参数的不同影响进行了重要讨论。

A new semi-analytical approach for nonlinear electro-thermo-mechanical dynamic responses of FG-GPLRC shallow spherical caps and circular plates with porous core

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.
