摘要：
A postbuckling analysis is presented for a uniaxially in-plane loaded, simply supported composite laminated rectangular plate resting on a "softening" non-linear elastic foundation. The analysis uses a perturbation technique to determine the buckling loads and postbuckling equilibrium paths, taking initial geometrical imperfection into account. Numerical examples cover the performances of perfect and imperfect, antisymmetrically angle-ply and symmetrically cross-ply, laminated rectangular plates in dimensionless graphical form.
