The analytical strip method (ASM) is extended in this paper to the buckling analysis of antisymmetric laminated composite plates with bending-extension coupling. A system of three equations of equilibrium governing the buckling response of antisymmetric laminated composite plates is reduced to a single eighth-order partial differential equation, expressed in terms of a displacement function. This equation is then solved analytically to generate the critical value of the in-plane forces (N-x, N-y) for antisymmetric cross-ply and angle-ply laminated and stiffened composite plates. The effects of various parameters, including plate aspect ratio, plate orthotropicity ratio, beam rigidity, and plate bending-extension coupling on the critical values of Nx and Ny on antisymmetric laminated composite plates are discussed. The results derived using the ASM are presented in tabular and graphical forms and compare very well with ones derived using finite-element analysis.
