Fluctuations and power-law scaling of dry, frictionless granular rheology near the hard-particle limit
A. P. Santos, Ishan Srivastava, Leonardo E. Silbert +2
The flow of frictionless granular particles is studied with stress-controlled discrete element modeling simulations for systems varying in size from 300 to 100,000 particles. The v…
Jamming of Bidisperse Frictional Spheres
Ishan Srivastava, Scott A. Roberts, Joel T. Clemmer +3
By generalizing a geometric argument for frictionless spheres, a model is proposed for the jamming density of mechanically stable packings of bidisperse, frictional spheres.…
Granular packings with sliding, rolling and twisting friction
A. P. Santos, Dan S. Bolintineanu, Gary S. Grest +4
Intuition tells us that a rolling or spinning sphere will eventually stop due to the presence of friction and other dissipative interactions. The resistance to rolling and spinning…
Viscometric flow of dense granular materials under controlled pressure and shear stress
Ishan Srivastava, Leonardo E. Silbert, Gary S. Grest +1
This study examines the flow of dense granular materials under external shear stress and pressure using discrete element method simulations. In this method, the material is allowed…
Evolution of Internal Granular Structure at the Flow-Arrest Transition
Ishan Srivastava, Jeremy B. Lechman, Gary S. Grest +1
The evolution of the internal granular structure in shear-arrested and shear-flowing states of granular materials is characterized using fabric tensors as descriptors of the intern…
Effect of Shape and Friction on the Packing and Flow of Granular Materials
K. Michael Salerno, Dan S. Bolintineanu, Gary S. Grest +4
The packing and flow of aspherical frictional particles are studied using discrete element simulations. Particles are superballs with shape that varie…
