Effect of collisional elasticity on the Bagnold rheology of sheared frictionless two-dimensional disks
Effect of collisional elasticity on the Bagnold rheology of sheared frictionless two-dimensional disks
We carry out constant volume simulations of steady-state, shear driven flow in a simple model of athermal, bidisperse, soft-core, frictionless disks in two dimensions, using a dissipation law that gives rise to Bagnoldian rheology. Focusing on the small strain rate limit, we map out the rheological behavior as a function …
