Plastic deformation of surface layer by sliding elliptical cylinder

Abstract

Steady-state plastic deformation of the workpiece surface layer by sliding of the elliptical rigid cylinder is simulated. The plane-strain theory of an ideal plastic solid with consideration of Prandtl’s contact friction is used. Contact pressure distribution and form of the plastic region are defined by the steady-state plastic flow condition. Significant effects of contact boundary curvature variation and contact friction on the distribution of contact pressure and the plastic deformation of a workpiece surface layer have been found.
