Abstract

Based on the von Karman-type plate theory a solution is formulated for the post buckling of an unsymmetrically laminated angle ply rectangular plate under inplane compression and edge shear. Opposite edges are assumed to be elastically restrained against rotation to the same degree. The transverse deflection and the force function in the governing equations of the plate are expanded into generalized double Fourier series. Using a procedure similar to that suggested by A. E. Green, all boundary conditions are satisfied. Numerical results for square plates under uniaxial and biaxial compressions are presented graphically for various rotational edge stiffnesses, high-modulus composite materials, numbers of layers and fiber orientation angles. The present results for simple boundary conditions are compared with previous results.
