Unsymmetrical indentation of an elastic half-plane in the presence of friction reversal L.M. Brock", H.G. Georgiadis\ N. Charalambakis^ o/Engmeerm# Mec/tomca, 50^-00^, CASVL Boz ^22, , Greece ABSTRACT Static rigid indentation of a linearly elastic half-plane in the presence of Coulomb friction that reverses its direction along the contact length is studied in this paper. A rigid punch, having an unsymmetrical profile in respect to its apex and no concave regions, slowly indents an elastic body even as it slides over it. Both a normal and a tangential force may be exerted on the indentor, therefore. In such a situation, depending upon the indentor shape and the relative magnitude of the external forces, a point at which the surface friction changes direction within the contact region, may exist.
