Abstract (EN): This paper presents a new three-dimensional damage propagation model for laminated composites. The initiation of failure is predicted using a state-of-the-art physically-based set of criteria, LaRC04. The novelty in this work lies in the modelling of failure propagation. So that the propagation of cracks with any orientation in a 3D space (as predicted by LaRC04) can be more accurately modelled, the strains are divided into their crack and elastic components. Mesh dependency is addressed using a smeared crack formulation with a characteristic length parameter. The model is implemented in the commercial software ABAQUS Explicit, so it can be readily used by designers and engineers. Validation and application examples will be presented at the conference.
