Апстракт:
A thermal buckling analysis of functionally graded thick rectangular plate is presented. Mechanical and thermal properties of the functionally graded material, except Poisson’s ratio, are assumed to vary continuously through the thickness of the plate according to a power-law distribution of the metal and ceramic volume fractions. Formulations of stability equations are based on high order shear deformation theory including shape function as well as von Karman type of non-linearity. An analytical method for determination of critical buckling temperature of plate is developed. Comparative results of critical buckling temperature for different type of shape functions are presented. The accuracy of the presented formulation and obtained numerical results is verified by comparing the results available in the literature. The effects of power-law index and temperature gradient on mechanical responses of the plates are discussed and appropriate conclusions are given.
