Calculation of friction for indenter with fractal roughness that slides against a viscoelastic foundation: Improved model

Abstract

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.
