Sliding contact of coated viscoelastic solids: model and experiment

Abstract

Abstract Sliding of a smooth indenter over a viscoelastic half-space with a rigid coating is considered. a Quasistatic contact problem is formulated, and a numerical-analytical solution method using the boundary element method and iterative procedure is developed. The dependence of the distribution of contact pressure and dissipative losses on the sliding velocity, coating thickness is analyzed. Friction of polyurethane materials (with rheological properties) coated by relatively hard carbon-based material is studied experimentally. Calculation results and experimental data have good qualitative correlation.
