Finite element analysis of a modified progressive damage model for composite laminates under low-velocity impact

In this paper, a 3D finite element model is established in ABAQUS/Explicit based on a modified progressive damage model to study the dynamic mechanical response and damage development in cross-ply composite laminates subjected to low-velocity impact. The 3D Hashin criterion and the damage evolution model with the through-thickness normal stress component σ33 are applied to predict the intra-laminar damage initiation and evolution. The cohesive...
