Abstract
This paper proposes a rate-dependent constitutive model for the kineti c sliding of frictional interfaces. The model is presented in the cont ext of a convected reference frame, which preserves frame indifference and is highly amenable to numerical implementation. The model feature s a state variable approach to the quantification of steady state slid ing, and a Perzyna viscoplastic regularization which introduces the Vi scous frictional behavior often observed in response to rapid slip rat e changes. Numerical aspects of implementing the model in a finite ele ment architecture are discussed. Through a series of simple slider and large deformation finite element simulations, the capability of the m odel to reasonably predict rate-dependent sliding behavior is demonstr ated.
