This paper concerns a dual domain decomposition approach, able to handle the presence of localized nonlinearity in an elastic solid, due to damage and fracture phenomena. The proposal extends the multi-time-step coupling method for structural dynamics, proposed by Gravouil and Combescure.

Abstract

This paper concerns a dual domain decomposition approach, able to handle the presence of localized nonlinearity in an elastic solid, due to damage and fracture phenomena. The proposal extends the multi-time-step coupling method for structural dynamics, proposed by Gravouil and Combescure. The main idea is to concentrate the non linearity due to dam-age at the interface level, there enforcing a non linear interface law.
