The coefficient of normal restitution in an oblique impact is theoretically studied. Using a two-dimensional lattice model for an elastic disk and an elastic wall, we demonstrate that the coefficient of normal restitution can exceed unity and has a peak against the incident angle in our simulation. We also explain this behavior based upon a phenomenological theory.

It is found that the tangential collision model, Cundall and Strack, being a rather complicated model, governed by 5 phenomenological parameters and 2 independent initial conditions, is described by 3 independent parameters only.
The Coefficient of Restitution Does Not Exceed Unity
We study a classical mechanical problem in which a macroscopic ball is reflected by a non-deformable wall. The ball is modeled as a collection of classical particles bound together by an arbitrary

With the aid of the simulation of a two-dimensional mechanical model, the equilibration process of a contact of elastic materials and a quasi-static collision of elastic materials are investigated.
Impact of a ball on a surface with tangential compliance
A simple model is presented to explain how the spin of a ball can be enhanced when the ball is incident obliquely on a flexible surface. The mechanism involves tangential distortion of the surface

The impact of a hard ball on a soft surface involves deformation of the surface, with consequent changes in the coefficient of restitution (COR) as the angle of incidence is varied. Experimental
