The formula of the simply-supported composite laminated plate under shearing buckling load is obtained by mainly using the theoretical background of the Galerkin method, and the result is verified and compared with finite element analysis.The theoretical shear buckling load for all edges simply-supported laminated plates are deduced. The theoretical results are matched well with ANSYS analysis. The derived formula is more suitable for the plates with the aspect ratio under 4,and the analytical formula in the paper is valuable to the engineering practice.
