In the present work a non-linear wear model for the contact between a cylinder rolling over a periodically varying surface is derived. The model is a pure contact model where the dynamics of cylinder and surface are neglected. With the aid of the derived model it can be shown, that even if the normal force, the traction and the creep are held constant, corrugation will evolve due to the non-linearities of the contact rnechanics. The model furthermore predicts the critical wave lengths for which the corrugation grows, and for which an initial corrugation is levelled out. Finally it is shown that the amplitude of the corrugation grows exponentially with a growth rate that for a given corrugation can be determined analytically.
