Based on a work by Knothe et al. (Wear 189 (1995) 91–99) a fully analytical solution for the temperature field, produced by sliding contact on the surface of a halfplane, is presented applying the Laplace transform technique. Further, the stress state in the halfplane under plane strain is analysed. A full solution is presented for the whole stress state as well as its extrema. All results are given in dimensionless form depending only on two parameters (dimensionless thermal penetration depth, Poisson's ratio).
