Abstract

Abstract

Kármán-type nonlinear large deflection equations are derived occnrding to the Reddy's higher-order shear deformation plate theory and used in the thermal postbuckling analysis The effects of initial geometric imperfections of the plate are included in the present study which also includes the thermal effects.Simply supported,symmetric cross-ply laminated plates subjected to uniform of nomuniform parabolic temperature distribution are considered. The analysis uses a mixed Galerkin-perlurbation technique to determine thermal buckling louds and postbuckling equilibrium paths.The effects played by transverse shear deformation plate aspeclraio, total number of plies thermal load ratio and initial geometric imperfections arealso studied.
