Phys. Rev. E 54, 5511–5515 (1996)Inelastic collapse of rotating spheresReceived 24 May 1996; published in the issue dated November 1996 Inelastic hard spheres can undergo an infinite number of collisions in a finite time. This process is called inelastic collapse. We consider the effect of rotation in this process and find that in contrast to the case of nonrotating spheres, collapse is possible for even large values of the coefficient of restitution and the angle formed by the colliding particles can be large. The limit to the nonrotating case is discontinuous. The three-body problem is solved analytically under the flat surface approximation and many-particle simulations are carried out. © 1996 The American Physical Society. © 1996 The American Physical Society URL:
