In this paper, we study theoretically and experimentally the friction between a rough parabolic or conical profile and a flat elastomer beyond the validity region of Amontons' law. The roughness is assumed to be randomly self-affine with a Hurst exponent H in the range from 0 to 1. We first consider a simple Kelvin body and then generalize the results to media with arbitrary linear rheology. Th...

The paper presents a combined experimental and theoretical approach to the understanding of hysteresis and adhesion contributions to rubber friction on dry and lubricated rough surfaces. Based on a proper analysis of the temperature- and frequency-dependent behaviors of nonlinear viscoelastic materials such as filler reinforced elastomer materials, master curves for the viscoelastic moduli are ...

Tyre wet skid resistance greatly affects vehicle safety, and it is dependent on the frictional behaviour at tyre–road interface; however, currently available numerical models, using finite element method, either neglect road roughness or obtain rightness expensive computed tomography scans, rendering them inefficient complex. This study aims to present an estimation method of rubber slides a ro...
