How Much Can We Simplify a System of Grains? [chapter]

Matthias Müller, Hans J. Herrmann
2001 Lecture Notes in Physics  
Realistic collisions between sand grains are very difficult to simulate correctly because many physical and mechanical nonlinearities occur. In order to simulate larger systems, many proposals have been made to treat collisions in a simplified form. Two of these models and some of the attached pitfalls are presented as well as success stories.
