摘要
Abstract
In this paper,the transient thermal stress distribution of variable property for two-dimensional functionally graded material (FGM) plates under non-uniform temperature field is investigated.The model for Al1 100-Ti6A14V-ZrO2 two-dimensional FGM plate is established and the finite element solution for 2D-FGM plate is constructed,which are obtained by calculating 1) the distribution of two-dimensional FGM plate transient thermal stress in different time transient;2) the distribution of variable property (component coefficient along the plate length and width direction) two-dimensional FGM plate transient thermal stress;3) under non-uniform temperature field (including constant temperature and linear temperature distribution,nonlinear temperature distribution and temperature distribution of periodic) the distribution of transient thermal stress in two-dimensional FGM plate.The present method can be used as a reference for calculating and analyzing the transient thermal stress for twodimensional functionally graded materials plate.关键词
