Damage propagation analyses of CFRP laminate subjected to out-of-plane load using a cohesive zone model

Abstract

QSI test analyses of CFRP laminate were carried out by FEM using interface elements considering cohesive zone model, which model delamination and matrix cracks. Damage propagation analysis was performed for four kinds of laminates with different geometries and stacking sequences, and the numerical results were compared with experimental results including relation between LPD and load, and delamination area. It was shown that the good correlation was obtained.
