It is widely known that a rubber friction shows not only a rate- and state-dependency but also a pressure-dependency, which is induced by surface roughness. In addition, a rate-dependency of shear strength (adhesion) owing to a viscoelasticity property of rubber is also essence. The authors has proposed rate- and state-dependent friction model capable of properly describing above-mentioned dependencies. In this study, we conduct numerical analysis of frictional sliding behavior of PDMS-PMMA contact using proposed model to demonstrate the validity of formulation. First, we show response characteristics of proposed model. We then compare frictional responses of proposed model with the experiment of sliding contact between rough semispherical PDMS and smooth PMMA plate.
