A multiscale computational strategy for assembly of structures in dynamics

Résumé

The aim of this work is to develop a multi-scale strategy for the simulation of structures assemblies subjected to transient dynamic loadings. The approach is based on the LATIN method with domain decomposition. The multi-scale LATIN method is a mixed method which deals at the same time with the forces and velocities at the interfaces of the different sub-domains. Already successfully applied to a variety of static problems, an extension of the method to dynamics is proposed. We first show how to adapt the multi-scale strategy to dynamics and in particular how to construct a macroscopic problem in space. Second, a specific treatment of the interfaces which leads to the continu-ities of the forces and velocities is developed. At last, we illustrate the performances of the method on a 1D wave propagation problem.
