Granular packing simulation protocols: tap, press and relax
A. P. Santos, Ishan Srivastava, Leonardo E. Silbert +2
Granular matter takes many paths to pack. Gentle compression, compaction or repetitive tapping can happen in natural and industrial processes. The path influences the packing micro…
Fractal dimensions of jammed packings with power-law particle size distributions in two and three dimensions
Joseph M. Monti, Ishan Srivastava, Leonardo E. Silbert +2
Static structure factors are computed for large-scale, mechanically stable, jammed packings of frictionless spheres (three dimensions) and disks (two dimensions) with broad, power-…
Large-scale frictionless jamming with power-law particle size distributions
Joseph M. Monti, Joel T. Clemmer, Ishan Srivastava +3
Due to significant computational expense, discrete element method simulations of jammed packings of size-dispersed spheres with size ratios greater than 1:10 have remained elusive,…
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.…
Flow and Arrest in Stressed Granular Materials
Ishan Srivastava, Leonardo E. Silbert, Jeremy B. Lechman +1
Flowing granular materials often abruptly arrest if not driven by sufficient applied stresses. Such abrupt cessation of motion can be economically expensive in industrial materials…
