On the constitutive modeling and finite element computation of rate-dependent frictional sliding in large deformations Original Research Article

This paper proposes a rate-dependent constitutive model for the kinetic sliding of frictional interfaces. The model is presented in the context of a convected reference frame, which preserves frame indifference and is highly amenable to numerical implementation. The model features a state variable approach to the quantification of steady state sliding, and a Perzyna viscoplastic regularization which introduces the viscous frictional behavior often observed in response to rapid slip rate changes. Numerical aspects of implementing the model in a finite element architecture are discussed. Through a series of simple slider and large deformation finite element simulations, the capability of the model to reasonably predict rate-dependent sliding behavior is demonstrated.
