Summary
Classic rigid body mechanics does not provide frictional forces acting in a 2D contact interface between two bodies during sticking. This is due to the statical undeterminacy related to this problem. Many technical systems, e.g. disk clutches, have such surface-to-surface contacts and it is sometimes desirable to treat them as rigid body systems despite the 2D contact. Alternatively, it is possible to model the systems using elastic instead of rigid bodies, but this might lead to certain drawbacks. A new regularization model of such 2D contacts between rigid bodies is proposed. It is based on the similarity to a material model for elasto-plasticity in continuum mechanics. Only dry friction is taken into account.
