Failure in Laminated Composite Plates Containing a Hole

Abstract

Investigation concerns the 3D stresses in a laminated composite plate weakened by a circular hole. The analysis is based on 3D macromechanical considerations. The debonding aspects are investigated between a fiber/matrix interface particularly in the region where the fiber intersects a free edge, e. g., the surface of a hole. The results, which are based on micromechanical considerations, are then used to predict the critical applied load stress which may cause initiation of ply-delamination. Keywords: Composite plates; Laminates.
