Abstract According to the macrostructure and microstructure of the composite laminates, a 3D finite element model for analyzing high velocity impact damage of composite laminates was established based on ABAQUS software platform. The cohesive elements were involved between two layers to simulate delaminations of the composite laminates, and a 3D visco-elastic constitutive model, coupled with Hashin failure criteria was used to predict the in-plane failure of composite laminates. By adopting this model, the ballistic performance and damage characteristics of composites laminates under high velocity impact were studied. The numerical results agree well with the experimental results. Parametric studies were conducted to study the effects of the strength parameters on the damage of composite laminates under high velocity impact. Some valuable conclusions were obtained.
