Granular physics
WebThe study of granular materials was totally absent from the physics literature until little more than a decade ago. In the late 1980s, Per Bak, Chao Taug, and Kurt Wiesenfeld published a now famous paper in Physical Review Letters, volume 59, page 381, 1987, proposing the theory of self-organized criticality, in which they used sand piles as a … WebNov 7, 2024 · Granular materials consist of macroscopic grains, interacting via contact forces, and unaffected by thermal fluctuations. They are one of a class systems that undergo jamming, i.e. a transition between fluid-like and disordered solid-like states. Roughly twenty years ago, proposals by Cates et al for the shear response of colloidal systems and ...
