摘要

Buckling analysis of rectangular thick functionally graded plates under mechanical and thermal loads is presented in this paper. It is assumed that the non-homogeneous mechanical properties vary linearly through the thickness of the plate. The plate is assumed to be under three types of mechanical loadings, namely; uniaxial compression, biaxial compression, and biaxial compression and tension and two types of thermal loadings, namely; uniform temperature rise and non-linear temperature rise through the thickness. The equilibrium and stability equations are derived using the third order shear deformation plate theory. Resulting equations are employed to obtain the closed-form solution for the critical buckling load for each loading case. The results are verified with the known data in the literature.
