Abstract

We discuss several models for granular particles commonly used in Molecular
Dynamics simulations of granular materials, including spheres with linear dashpot force, viscoelastic
spheres and adhesive viscoelastic spheres. Starting from the vectorial interaction
forces we derive the coefficients of normal and tangential restitution as functions of the
vectorial impact velocity and of the material constants. We review the methods of
measurements of the coefficients of restitution and characterize the coefficient of normal
restitution as a fluctuating quantity. Moreover, the scaling behavior and the influence of
different force laws on the dynamical system behavior are discussed. The powerful method of
event-driven Molecular Dynamics is described and the algorithmic simulation technique is
explained in detail. Finally we discuss the limitations of event-driven MD.
