Large deflection of composite laminated plates under transverse and in-plane loads and resting on elastic foundations

摘要

A large deflection analysis is presented for a simply supported, composite laminated thin pate subjected to combined uniform lateral pressure and compressive edge loading and resting on a two-parameter (pasternak-type) elastic foundation. The formulations are based on the classica laminated pate theory, and including the pate-foundation interaction. The analysis uses a perturbation technique to determine the load-defection curves and load-bending moment curves. Numeric examples are presented that relate to the performances of antisymmetricaly angle-ply and symmetrically cross-ply laminated plates subjected to combined loading and resting on tow-parameter elastic foundations from which results for Winkler elastic foundation stiffness, the pate aspect ratio, the total number of pies, fiber orientation and initial compressive load is studied. Typical results are presented in dimensionless graphical form.
