- Abstract
Within the analysis of many frictional contact problems Coulomb's law with a constant friction coefficient μ is used. This assumption is sufficient for many applications in structural mechanics; however in the special case of rubber friction on rough surfaces the resulting simplification cannot be accepted. The physical interactions between e.g. a tire and a road surface are very complex and still widely unknown. The elastomer undergoes large deformations during contact, such that the frictional properties result for the main part from internal energy dissipation and not just from the combination of surfaces in contact like e.g. adhesion. As it is apparent from experiments, the friction coefficient depends heavily on various parameters like sliding velocity, surface roughness, normal forces and temperature change. In this contribution a multi-scale approach will be used to make an attempt to understand the sources of elastomere friction in a more rigorous way.
