Buckling and postbuckling behavior of composited skew plates while compressing and shearing is analyzed. The plan view of plate is a parallelogram with different boundary condition along the contour. The technique of definition of buckling and load-carrying capacity is developed for panels of skew forms. The problem of buckling is solved in movement by dint of Reitz method. While analysis of the post buckling behavior of a plate the surface shape has been taken equal to first own mode of buckling. Nonlinear displacements have been computed with the use of the well-known finite difference method. Load-carrying capacity of the plate has been calculated with the use of the Tsai-Wu criterion.
