摘要

•A novel layered finite element model is established for predicting the damage behavior of MLC.•Cohesive and GTN model are used to predict the damage behavior of interface region and metal matrix.•The reliability of the proposed finite element model is verified by the in-situ tensile test.•The effect of wave interface structure on the damage behavior of Ti/Al MLC are revealed.
