The present work is concerned with the modeling of progressive damage in fiber reinforced polymer laminates and the implementation into a finite element code as constitutive material law. The objective is to predict damage evolution and material degradation due to matrix dominated failure modes ("matrix cracking"). In a previous work, a ply-level continuum damage model based on ply failure mechanisms postulated by Puck has been presented. In the current work, the damage model is adapted for arbitrary loading paths and implemented as a constitutive law with the finite element method. This way, complex structures can be analyzed and their damage behavior including load redistribution due to damage can be studied. To demonstrate the utilization of the damage model in structural analysis, it is applied in the simulation of an open hole compression test and the results are compared to experimental data from the literature.
