The paper presents a numerical model to investigate wear under partial slip conditions for smooth and rough contacting bodies. The wear simulation is based on the Archard wear law and is applied to a sphere on a flat geometry. In this numerical model, an analytical simulation of roughness is considered, which even for small magnitudes, is an important factor that cannot be neglected. The effect of an elastic perfectly-plastic material is also considered to limit the peaks of pressure on each contacting asperity.
