Granular theory
http://web.mit.edu/kkamrin/www/granular.html 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 … See more Granular matter is a system composed of many macroscopic particles. Microscopic particles (atoms\molecules) are described (in classical mechanics) by all DOF of the system. Macroscopic particles are described only by … See more Granular systems are known to exhibit jamming and undergo a jamming transition which is thought of as a thermodynamic phase transition to … See more Granulation is the act or process in which primary powder particles are made to adhere to form larger, multiparticle entities called granules.
