The covariant contact description is applied to incorporate the treatment of contact problems into the high‐order finite element technique. A hierarchical enrichment of the Ansatz space allows to construct a contact layer finite element combining both an exact geometry for contact surfaces, and a mesh with linear Ansatz functions for the interior of the contacting bodies. Good correlation with the Hertz problem is shown even within a few contact elements for the contact zone, however, not in general. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
