Abstract

Abstract

In this paper,general equations relating to the stability of laminated plates of symmetric cross-ply with initial imperfection factors are derived by using the variational principle.Taking the deflection as the perturbation parameter,the equilibrium path of the post-buckling path of a simply supported rectangular plate is investigated with the perturbation method.An approximation expression and a typical numerical example are presented to manifest the post-buekling behavior of the rectangular plate.
