Abstract: An analysis for th:postbuckling bahavior of antisymmetrically laminated angle-ply rectangular plates with various boundary conditions is presented by making use of the pertuxbation tschniquc.The nondimensional maximum deflection is selected as.the perturbation parameter. A solution of perturbation differential equation of higher-order approximation is assumed in the form of double Fourier serics consisting of the beam function.This method is very efficient and the i.umcrical results show good convergence and reliability of the present solution.
