摘要
The postbuckling behavior of antisymmetric angle-ply plates, resting on sumple supports and subjected to a gradually increasing uniform temperature field is investigated. Stable equilibrium configurations are determined through a direct application of the principle of minimum potential energy. Since nonunique equilibrium states may exist, a method of incremental loading is employed to identify the particular state associated with a given thermal loading path. Numerical results of fiber-reinforced laminates illustrate the effects of ply orientation, number of layers and aspect ratio on the postbuckling behavior. The phenomena of secondary buckling is examined in detail.
