Because of their high specific strength and stiffness, fiber-reinforced plastics is used as structural members in various fields, and hence analysis of thin laminated structures is important. Post buckling behaviors of laminated plates under uniaxial compression have been discussed by many researchers. However, little research has been performed on the post buckling behavior of laminated curved plates. In this paper, the stability condition of CFRP angle-ply laminated curved plates under uniaxial compression and which are simply supported along four edges is determined using Galerkin's method. The post buckling behavior is proven analytically, and the effects of various factors, such as the dimension of the curved plate, deflection pattern, average axial shortening and amplitudes of initial imperfections, are clarified.
