Shear banding, discontinuous shear thickening, and rheological phase transitions in athermally sheared frictionless disks
Shear banding, discontinuous shear thickening, and rheological phase transitions in athermally sheared frictionless disks
We report on numerical simulations of simple models of athermal, bidisperse, soft-core, massive disks in two dimensions, as a function of packing fraction ϕ, inelasticity of collisions as measured by a parameter Q, and applied uniform shear strain rate γ[over ̇]. Our particles have contact interactions consisting of normally directed …
