【Abstract】 An analysis for the postbuckling behavior of antisymmetrically laminated angle-ply rectangular plates with various boundary conditions is presented by making use of the perturbation technique. 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 scries consisting of the beam function. This method is very efficient and the numerical results show good convergence and reliability of the present solution.更多还原
