Abstract

This article deals with the calculation and administration of contact between many moving bodies in the planar case. The main issue is the contact determination between bodies of either round or polygonal shape. The modeling is done by means of molecular dynamics to investigate the motion of many bodies very efficiently. Besides elastic normal forces, which prevent penetration of the bodies, damping forces and adhesion is described and considered for the computations. Our interest is directed toward collision detection. By means of sorting algorithms, neighboring bodies are found easily and, therefore, systems consisting of a large number of bodies can be determined efficiently.
