Abstract

The purpose of this paper is to construct models capable of predicting the growth of delaminations in thick laminates subjected to a low-velocity impact. Experimental evidence contain herein suggests that these delaminations are initiated at the intersections of matrix cracks with the ply interfaces. Utilizing this observation, a nonlinear computational finite element scheme is developed to predict the delamination evolution in plates scenario using a laminate composed of graphite/epoxy. Both matrix cracks and delaminations are modeled using a laminated composed of graphite/ epoxy. Both the matrix cracks and delaminations are modeled using a nonlinear interface failure criterion previously proposed by Needleman (1987).
