Multi-scale models based on computational homogenisation are nowadays developed for the simulation of complex material behaviour. The use of homogenisation techniques on finite-sized representative volume elements in the presence of quasi-brittle damage may lead to the presence of snap-backs in the macroscopic material response. A methodology to simulate this type of response in the multi-scale technique is proposed, based on the control of the dissipation at the mesoscopic scale.
Des schémas multi-échelles basés sur des principes d'homogénéisation numériques sont actuellement développés pour la simulation de comportements matériels complexes. L'utilisation de techniques d'homogénéisation sur des éléments de volume représentatifs de tailles finies en présence d'endommagement quasi-fragile peut causer l'apparition d'effets de snap-back dans la réponse matérielle macroscopique. Une méthode est proposée permettant d'introduire ce type de réponse dans un schéma multi-échelles, basée sur le contrôle de la dissipation à l'échelle mésoscopique.
