In FEM analysis of rolling contact problems Arbitrary Lagrangian‐Eulerian (ALE) methods are the state of the art. These methods allow mesh refinements concentrated to the contact region and offer a time independent formulation of stationary elastic rolling. The relative‐kinematic description of rolling leads to a relative motion between finite element mesh and material points. Thus in contrast to a pure Lagrangian description of rolling the relative movement of the material particles is not determined directly. The contact problem is assumed as deformable‐rigid and its contact constraints are included by the penalty‐method. For the computation of the frictional tire‐road contact the slip velocities have to be integrated along the pathlines of the material particles. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
