slip-weakening laws and apparent static friction coefficient
Abstract eng: Solutions are described for tangentially loaded contact problems in which the coefficient of friction transitions from a static to a dynamic value over some small but finite slip displacement. Numerical and analytical result for a Hertzian geometry show that the maximum tangential force occurs before all the contact slips, and that the maximum macroscopic friction coefficient is lower than the pointwise value. If the transition occurs over a small slip distance, the assumed behaviour is mathematically analogous to a mode II fracture criterion.
