In this paper, a discrete method for analyzing the geometrical nonlinear problem of laminated shallow shells is proposed. The discrete solutions of partial differential equations governing the geometrical nonlinear behavior of laminated shallow shells are obtained in discrete forms. By transforming the differential equations into integral equations and applying the numerical integration, the discrete solutions can be obtained. The nonlinear problems are solved by the iteration and the displacement incremental procedure. As the application of the present method, geometrical nonlinear problem of laminated elliptic paraboloidal shallow shells are calculated. The numerical results obtained by this method are verified to be in good agreement the other solution. Moreover, symmetrical and unsymmetrical buckling behavior of laminated shallow shells are shown.
