摘要: Abstract This article investigated numerically the postbuckling load parameter of functionally graded shell panels under uniform and non-uniform thermal environment using nonlinear finite element method. The structure is assumed to be three different fields (uniform, linear temperature) across panel thickness including temperature dependent properties each constituent. effective material are evaluated micromechanical rule (Voigt type) in association with power-law distribution Further, model mathematically based on higher-order mid-plane theory Green-Lagrange strain deformation relations. excess distortion has been included by taking all strains. equation in-plane derived minimizing total potential energy expression. desired parameters computed help a suitable MATLAB code present conjunction direct iterative accuracy proposed numerical solutions have checked initially extended show significance complex mathematical solving various examples for geometrical parameters.
