This study examines the distribution of contact forces in dense granular flows and finds that higher magnitude contact forces exist in faster flows with stiffer grains. A proposed physical mechanism explains this rate-dependent force transmission, establishing a relationship between contact forces and grain velocities. This analysis provides a starting point for unifying a range of continuum models based on either contact forces or grain velocities.
Dense granular flows are well described by several continuum models; however, their internal dynamics remain elusive. This study explores the contact force distributions in simulated steady and homogenous shear flows. The results demonstrate the existence of high magnitude contact forces in faster flows with stiffer grains. A proposed physical mechanism explains this rate-dependent force transmission. This analysis establishes a relation between contact forces and grain velocities, providing an entry point to unify a range of continuum models derived from either contact forces or grain velocity.
