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 DOF of the motion of each particle as a rigid body. In each particle are a lot of internal DOF. Consider inelastic collision between two particles - the energy from velocity as rigid body is transferred to microscopic internal DOF. We get “Dissipation” - irreversibl… WebMay 1, 2024 · Besides, several multiscale models based on statistical mechanics have also been developed in the last years (cf. [29], [30], [31]).
