International audience; We are interested in the modeling of frictional impact problems. This Note presents an approach which reconciles the speed of resolution (semi-explicit calculation) and the accuracy of contact modeling by the bi-potential meth

To make possible the Finite Element computation of Representative Volume Elements (RVE) of composites with a complex microstructure, we first propose to mesh the volume independently of the considered microstructure. Homogeneous elastic properties ar
