Abstract
The interest of this study is the analysis of the thermal buckling problem of porous thick rectangular plates made of FGM material using high order shear theory. Material properties like Young's modulus and coefficient of thermal expansion of the plate are assumed to vary continuously in the thickness direction as a function of the volume fraction of the constituents defined with the modified mixture rule including the volume fraction of porosity with three different types of porosity distribution.The equilibrium and stability equations are obtained based on the present theory. The nonlinear governing equations are solved for simply supported plates. The thermal loads are assumed to be uniform, linear and non-linear distribution across the thickness. A parametric study will be carried out in order to underline the effects of the various parameters governing the response of thick FGM plates on the critical buckling temperature.
