| Abstract: | We study numerically the dynamical evolution of a system of colliding bodies. Collisions are inelastic and the coefficient of rebound is a function of the impat velocity. Various functions are used. The system can reach an equilibrium state characterized by a finite thickness independently on the sense of variation of the functions. Within the frame of various distributions of the body sizes we observe a segregation rather than equipartition of the kinetic energy of random motions. |
