The anomalous behavior of coefficient of normal restitution in the oblique impact
arXiv:cond-mat/0310058 · doi:10.1103/PhysRevLett.93.154301
Abstract
The coefficient of normal restitution in an oblique impact is theoretically studied. Using a two-dimensional lattice models for an elastic disk and an elastic wall, we demonstrate that the coefficient of normal restitution can exceed one and has a peak against the incident angle in our simulation. Finally, we explain these phenomena based upon the phenomenological theory of elasticity.
