Delamination is one of the most common types of damage in structural collapse. To model the initiation and the propagation of delamination, a method of embedding the cohesive zone model in finite element formulation based on nonlinear explicit dynamic algorithm is employed, and the model is formulated in the context of Damage Mechanics. The cohesive elements are placed between layers of solid finite elements, and the 3D material interface delamination under mixed-mode ratio loading can be simulated. Benzeggagh-Kenane´s propagation criterion is adopted to calculate the final displacement jump, and Turon´s initial damage surface criterion is adopted to calculate the onset displacement jump. The numerical predictions given by the formed code CVFEM are compared with those obtained from Abaqus 6.7.
