A Study of the Equation of State for Copper.

Abstract

The equation of state of copper was studied by using computer simulations. An existing molecular dynamics program written for the Cray was modified to run on both the VAX and on a parallel processing system. The program applied the embedded-atom method to determine interatomic forces. Experiments on the VAX found the copper melting point to be very near 1350 k which is close to the known melt point of 1357.6 k. Measurements taken on both types of computers showed that parallel processing offers a time savings factor of 3.75 over serial processing systems.
