Abstract : A new approach for sub-mesh enrichment of the contact geometry has been proposed in the framework of the Finite Element Method and the Node-to-Segment contact discretization. The method is very general and multipurpose : it allows, for example, to extend the limits of the contact modeling of thin-walled structures or to account for a change of the contact geometry due to loading, for example, to simulate a shallow wear.
