Abstract

QSI test analyses of CFRP laminate were performed by FEM using interface elements considering cohesive zone model (CZM), which models delamination and matrix cracks. Damage propagation analyses for four different kinds of laminates were conducted by both implicit and explicit methods considering materially, geometrically and boundary nonlinear. QSI test analyses can be performed by the implicit method using Zig-zag CZM, and the results are almost the same as the explicit method using bi-linear CZM. Moreover, the numerical models were validated through comparison with experimental results including the relation between the load point displacement and applied load, and delamination area.
