Calculation of Friction for Indenter with Fractal Roughness that Slides against a Viscoelastic Foundation: Improved Model

摘要

Additional results on calculating the deformation force of friction for a rough indenter sliding on a viscoelastic foundation are presented. The results consider the influence of the roughness on the normal contact load. As in earlier studies, the deformation properties of a foundation are described by the Kelvin model and the roughness of an indenter is represented by the Cantor-Borodich fractal, which consists of a set of rectangular asperities.
