Abstract

In typical geotechnical applications dealing with structure/soil interaction, Coulomb's frictional law is usually used. However, in many cases such a simple model may be inadequate. In this paper friction laws are developed which allow for `hardening' of the slip surface. The models are developed by simulating plastic deformations of the microstructure in the contact zone between two sliding rough surfaces with asperities. On the basis of the computed responses frictional laws are developed, which show physically relevant deviations from the Coulomb model.
