The 3-D contact problem for an elastic sphere rolling over a thin viscoelastic layer bonded to an elastic half-space is considered. The Kelvin model is used to describe the layer viscoelastic properties in tangential direction. The layer compliance in normal direction is described by the Winkler model. The contact region is assumed to consist of a stick and slip subregions, which boundaries are unknown in advance. The contact stress distributions were studied for various values of sliding friction coefficient, relative slippage and the layer viscosity parameters. https://cm2018.org/#program
