Abstract

The postbuckling behavior of geometrically imperfect laminated plates with non-linear viscoelastic materials is investigated. The relaxation properties for the various Schapery single-integrals of a unidirectional layer are derived from the stress-relaxation curves obtained in part I. The non-linear plate (von Karman) equations are derived symbolically using Mathematica in the form of a system of first-order non-linear differential equations. A numerical example of graphite/epoxy cross-ply laminates is presented and discussed.
