Abstract

Abstract: The paper presents a model to analysis the failure process of laminated composite plates and shells. Large deformation, local failure of material and their interaction are considered in the model. Based on the model and the finite element method, the buckling load, the postbuckling path and the catastrophic failure load of laminated composite plates and stiffened composite plates subjected to inplane loading were analysed.

Key words: composite materials, ribs (supports), buckling, damage
