The present paper contributes to the modeling of contacts with viscoelastic materials. An indenter is pressed into an elastomer and slides on its surface with a constant velocity. Contact regions typically experience periodical loading due to surface roughness with characteristic length scales. Loading within a medium frequency range is studied, in which the viscous properties of the elastomer dominate. After passing a transition zone a stationary state is reached. An one‐dimensional model is used to determine estimations for the indentation depth and the coefficient of friction. Results for two simply shaped indenters are presented and compared to boundary element simulations.
