Abstract

This paper presents the derivation of a model for the prediction of the coefficient of friction for two elasto-plastic surfaces in quasi-steady-state sliding. A companion paper presents numerical results and a discussion on the implications of the model's predictions in comparison with selected experimental data. The model considers the separate effects of asperity interaction and deformation, debris interaction and plowing, and adhesion, with partitioning of normal load (and contact areas) between different contacting elements. The analysis is restricted to nominally "steady state" sliding where the contact parameters are statistically invariant. The modifier "quasi" is used to emphasize that in tribodynamic systems there is no true equilibrium condition in which the frictional effects are "constant".
