Abstract :
The relaxation processes in a granular matter confined in a closed container in space under gravity is investigated numerically by means of the ED-algorithm. To simulate the system behavior a model of identical hard elastically interacting spheres is used. The system transition to thermodynamic equilibrium is considered in detail. Oscillatory nature of the relaxation processes is established and explained. The conditions of the oscillations absence are ascertained.
