Surface Deformation Considerations for Rolling with Incipient Sliding

Attention is focused on the material’s response to stress (normal and tangential) in connection with the modelling of material removal by wear as well as the resulting frictional force to produce sliding. Tribological models are confined generally to relative motion in pure sliding where the surface material of one body is in continual contact with the passing of the surface material of another body. The case of combined rolling and sliding (particularly incipient sliding), while important from a practical perspective, may also be very useful for tribological model development.
