Molecular dynamics is used to study the response of single crystal copper target to impacts by single crystal copper at velocities in the range 1 km/s to 3 km/s. The Embedded Atom Method (EAM) potential by Foiles et al. for Cu 1 was used in the simulation. The potential and its implementation in the open source, Large-scale Atomic Molecular Massively Parallel Simulator (LAMMPS) 2 was verified by reproducing the experimental values of bulk modulus of Cu. The shock velocity (u(s)) as a function of particle velocity (u(p)) matches published experimental and molecular dynamic simulations results.
