Abstract:

This Rapid Communication highlights the physical processes at the origin of the constitutive law of dense granular flows. In simulated plane shear flows, we present a micro-mechanical expression for the phenomenological friction law μ(I). The expression highlights two distinct pathways for momentum transport-through either balanced contact forces or grain micro-acceleration. We show that these two rate-dependent processes control and explain the friction law. This understanding may help advance rheological models for granular materials and other soft materials such as emulsions and suspensions.
