Résumé

On the basis of a classic LDEM model and a recently developed implicit integration algorithm, a study of the response of a quasi-brittle RVE under compression is exposed. This study serves as context to compare different formulations of the local failure criterion of the lattice cohesive links. Beforehand a complete identification procedure of the formulations parameters, based on simple simulations, is detailed. Finally, a formulation is retained and used to investigate deeper the compression response of LDEM, considering different boundary conditions.
