In this paper, the stability of laminated composite plates was studied by a partial hybrid plate element based on higher order plate theory. The transverse shear deformation and the warping of cross section are both considered by the higher order plate theory. Moreover, the element stiffness is formulated by only assuming transverse shear stress field, while the flexural stresses from assumed displacement field. Consequently, the interlaminar transverse shear discontinuity is overcome. On the other hand, the buckling load is assumed to be uniform through thickness in-plane stresses in this study. The Green-Lagrangian strains, instead of Von Karmon strains, are then adopted to take the nonlinear in-plane deformations into account. Numerical results are presented for several benchmark problems including various span-to-thickness ratios, stacking sequences, boundary conditions, and loading cases.
