Summary
A two-dimensional finite element model for the rolling contact of a wheel on a rail
is presented that accounts for the roughness of the contact surfaces. A fully elasticplastic
material description enables the computation of the heavily deformed layer
observed in metallographic investigations of rolling sliding contacts. It can be shown
that this layer is produced as a result of the contact of asperities and superimposes
the contact mechanical deformation arising from the rolling sliding contact of flat
surfaces. The roughness model is compared to a flat model and the prediction of the
surface deformation is compared to metallographic investigations.
