The study is based on a homogenisation technique by scale transition allowing taking into account the microstructure and an evaluation of the damage by appearance of heterogeneities having null mechanical properties. The self-coherent model is reformulated in incremental approach. The incremental scheme consists of a progressive introduction of inclusions ; a self-consistent calculation is realized with each step. The applications presented, as well in one-site as multi-site show improvement in terms of prediction of the effective properties. The second part of this work introduces the damage by the formulation of two models of degradation. The of rupture, takes into account two criteria of rupture : a first criterion on the maximum princip...
