Abstract

An elastic punch, modeled as a semi-infinite strip, moves with constant speed over the surface of a semi-infinite elastic body. Using the plane strain theory of elasticity, we obtain the resulting stress distribution along the interface of the contacting bodies for different material combinations and a range of sliding velocity and frictional coefficients. It is found that both the stress intensity factor and the order of the singularity depend on sliding velocity as well as on the other parameters. Speed-dependent composite material parameters are defined which determine the orders of the singularities.
