Prediction of the friction coefficient of filled rubber sliding on dry and wet surfaces with self-affine large roughness

The friction of filled rubber on a rough surface is mainly determined by the rubber viscoelasticity and the surface property of multiple-scale asperities that can be represented by the power spectral density of the surface profile (i.e., power spectrum of surface roughness). This paper investigates...
