Abstract

Based on Von Karman strain-displacement relations and variational principles, the FEM formulations, which are used to analyze the thermal buckling, and thermal postbuckling of composite plates with embedded SMA are presented in this study. The recovery stress and young modulus are calculated by one-dimensional constitutive model. Some numerical examples are also presented. The results indicate that activated SMA can suppress the thermal buckling of the plates and reduce thermal postbuckling deflections.
