The present study describes the basic principles of a general damage approach for laminates and demonstrates its prediction possibilities for simulating the complete fracture phenomenon in the case of the initiation and propagation of delamination. In this paper, the Damage Mechanics Approach is presented to solve delamination problems such as the propagation of an initiated crack or the initiation of delamination around holes. For the M55J/M18 carbon/epoxy material, numerical simulations are presented and compared with experimental results.
