Abstract
Theoretical models for surface mobility are derived using two alternat ive approaches: time averaged input power and effective mobility. The surface mobility of a circular contact area of an infinite plate is in vestigated for both uniform conphase contact force and uniform conphas e contact velocity. In the latter case the mixed boundary value proble m is circumvented by using a discretized model to find the force distr ibution. The theoretical values of surface mobility for a circular are a with uniform conphase contact velocity are compared to experimental measurements made on a simulated infinite plate.
