Abstract

The effect of surface roughness on contact is studied by analyzing indentation of a single crystal by a rigid indenter with a square wave profile. Calculations are carried out using discrete dislocation plasticity and, for comparison purposes, conventional continuum crystal plasticity. A size independent response is obtained using conventional crystal plasticity whereas discrete dislocation plasticity gives a distinct size effect with smaller being harder.
