WebMar 1, 1999 · PDF - Granular matter refers to particle systems in which the size d is larger than one micron. Below one micron, thermal agitation is important, and Brownian motion can be seen. Above one micron, thermal agitation is negligible. We are interested here in many-particle systems, at zero temperature, occupying a large variety of metastable states: if … WebOct 31, 2000 · Abstract. Granular materials, such as sand, gravel, powders, and pharmaceutical pills, are large aggregates of macroscopic, individually solid particles, or “grains.”. Far from being simple materials with simple properties, they display an astounding range of complex behavior that defies their categorization as solid, liquid, or gas.
