We introduce a two-scale computational strategy for the resolution of contact problems with
friction, possibly with numerous contact surfaces; the structure studied may also be highly
heterogeneous. The description of “micro” and “macro” quantities is performed on the
interfaces arising from the decomposition of the structure studied into an assembly of
substructures and interfaces. The efficiency and robustness of the method are illustrated on
several examples. This iterative computational strategy is suitable for parallel computing; it …
