Buckling of Rectangular Symmetric Angle-Ply Laminated Plates Determined by Eigensensitivity Analysis

摘要

Closed-form approximate solutions for uniaxial and biaxial compressive buckling of rectangular symmetric angle-ply laminates are developed from eigensensitivity analysis. Boundary conditions, which consist of the various combinations of clamped and simply supported edges, are incorporated through appropriate edge condition parameters. Calculated results, presented for elastic moduli ratios up to 40, compare quite favorably with the corresponding buckling loads obtained from the Ritz method.
