In the buckling analysis of laminated composite plates, the classical thin plate theory and several shear deformation theories have been proposed. In the present study, the higher-order shear deformation theory was used with the parabolic distribution of the transverse. The pb-2 Ritz function being consisted of the product of a basic function and a two-dimensional polynomial function has been used to represent an arbitrary edge condition. The buckling analysis of anti-symmetrical and unsymmetrical laminated compression. The effects of boundary conditions, material anisotropy, plate thickness and the shear loading direction were investigated and the buckling modes were represented. It was shown that the present method could be widely used to analyze the buckling behavior of laminated composite plates.
