On the benefits of a multiscale strategy to model-order reduction for frictional contact problems

In this work, the efficiency of a multiscale strategy based on a domain decomposition method (DDM) for model-order reduction of friction contact problems is presented. The resolution strategy is based on the LATIN method combined with the Proper Generalized Decomposition (PGD). The effectiveness and possible improvement points of the method will be illustrated on a one-dimensional frictional benchmark problem which features a large frictional contact interface and sliding front.
