Abstract

Abstract

In this paper,Dynamic Relaxation Method is applied to study the postbuckling path of cylindrically curved panels of laminated composite materials during loading and unloading.The phenomenon that loading paths do not coincide with unloading paths has been found.Numerical results are given for cylindrically curved cross-ply panels subjected to uniform uniaxial compression under two types of boundary conditions.The influence of the number of layers,the panels curvature and the initial imperfection on the postbuckling paths is discussed.
