Granular material - Wikipedia

A granular material is a conglomeration of discrete solid, macroscopic particles characterized by a loss of energy whenever the particles interact (the most common example would be friction when grains collide). The constituents that compose granular material are large enough such that they are not subject to thermal motion fluctuations.

Granular Materials - PhysicsCentral

Granular materials form what are called "collective" systems, because the particles' touching and rubbing together is so important in determining what happens. In a sandpile, for instance, each particle touches only a few others, but these "short range" interactions determine what happens to the whole pile.

Granular Material - an overview | ScienceDirect Topics

Granular materials have been recently defined as a "new state of matter" [1]. The justification of this notion is the fact that granular materials exhibit a large number of properties and states which differ very significantly from those of their molecular counterparts.

Granular material - OilfieldWiki

Granular gases. If the granular material is driven harder such that contacts between the grains become highly infrequent, the material enters a gaseous state. Correspondingly, one can define a granular temperature equal to the root mean square of grain velocity fluctuations that is analogous to thermodynamic temperature.
