Abstract: An analytical model of friction under combined linear sliding and spin of the contact area is presented. It is shown that the model, although based on simplifying assumptions, predicts reasonably ...

Abstract: The paper presents an investigation into producing the self-levitation effect using piezo-electric actuators (PZTs). Self-levitation has been demonstrated and results are presented and discussed. A ...

Abstract: A series of experiments are described where combined linear and rotating motions are imposed upon a polymer while it is in contact with a smooth and clean counterface. Friction data are ...
