The accuracy problem of three local displacement modes of the global-local higher order deformation theory is investigated.Based on the higher-order shear deformation theory, the global-local 1, 3、 2, 3、 and 1, 2 modes are derived.Satisfying the continuity of in-plane deformation and shear stress as well as the free conditions of the upper and lower surfaces.Compared to the global-local 1, 2-3 mode, for the angle ply laminates, the number of the independent variables of each node is reduced from 13 to 11, which does not change with the number of plies.
