Ultrastable Shear-Jammed Granular Material
Ultrastable Shear-Jammed Granular Material
Dry granular materials such as sand, gravel, pills, or agricultural grains, can become rigid when compressed or sheared. At low density, one can distort the shape of a container of granular material without encountering any resistance. Under isotropic compression, the material will reach a certain {\it jamming} density and then …
