摘要: In this paper, applying perturbation method to von Karman-type nonlinear large deflection equations of orthotropic plates by taking deflection as perturbation parameter, the postbuckling behavior of simply supported rectangular orthotropic plates under in-plane compression is investigated.Two types of in-plane boundary conditions are now considered and the effects of initial imperfections are also studied.Numerical results are presented for various cases of orthotropic composite plates having different elastic properties.It is found that the results obtained are in good agreement with those of experiments.
