Shear-Jamming in Two-Dimensional Granular Materials with Power-Law Grain-Size Distribution
Although substantial progress has been made in recent years in research onsheared granular matter, relatively few studies concentrate on the behavior of materials withvery strong polydispersity. In this paper, shear deformation of a two-dimensional granularmaterial composed of frictional disk-shaped...
