Abstract
The computation of the stress and strain of a rolling wheel on the rail requires the
thorough analysis of the contact condition including slip. Prom the physical point
of view it is important to use an appropriate description of the surface roughness
and to take account of the rolling condition because this differs significantly from
static contact. As a first approach a two dimensional model of a wheel running
with constant velocity over an infinite elastic strip is investigated. Because of
the necessity to use a dense mesh in the contact
