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

If the granular material is driven harder such that contacts between the grains become highly infrequent, the material enters a gaseous … See more

Excited granular matter is a rich pattern-forming system. Some of the pattern-forming behaviours seen in granular materials are:
• The un-mixing or segregation of unlike grains under vibration and flow. An example of this is … See more

Coulomb friction Law
Coulomb regarded internal forces between granular particles as a friction process, and proposed the friction law, that the force of friction of solid particles is proportional to the normal pressure between them and … See more

Granular systems are known to exhibit jamming and undergo a jamming transition which is thought of as a thermodynamic phase transition to a … See more

Granulation is the act or process in which primary powder particles are made to adhere to form larger, multiparticle entities called granules. See more

When water or other liquids are cooled sufficiently slowly, randomly positioned molecules rearrange and solid crystals emerge and grow. A … See more
