Abstract：In this paper, cohesive zone model is used to study the delamination of FMLs under low-velocity impact. The model owns two main advantages: one is that no initial crack is needed to be assumed; another is that there is no need to remesh the model during the crack propagation. First, to validate the cohesive zone model in dealing with delamination of composite laminates, the delamination simulation is carried out under the low-velocity impact and a relative good agreement is achieved with the experimental data. Next, the delamination of FMLs with different metal ratios is investigated under low-velocity impact and the results are compared with that of composite laminates. Last, the effects of stacking structures and metal ratios towards the delamination of fiber/metal laminates are studied according to the principle of energy balance.
