2D DEM of Ice Rubble: the effect of rate-dependent friction.

The friction coefficient of ice on ice is usually modeled as a constant. However, theory and experimental data show that ice-ice friction depends on the speed of sliding. In this paper we incorporate a rate-dependent friction coefficient into 2D discrete element method simulations of ice ensemble be...
