Particle packing simulations based on Newtonian mechanics

A program to simulate the packing of round particles was made in the course of this work. The theoretical packing of the particles was studied in 3-dimensional situations with the program. The effects of friction, elasticity, size and spring co-efficient on packing were examined. It was observed that increased friction caused decreased packing density. Elasticity had a minor effect on the density, while the spring constant defining the interactions between particles had a minimal effect. (C) 2007 Published by Elsevier B.V.
