In order to study the microscopic deformation behavior of materials, numerical simulations such as the molecular dynamics (MD) method, Monte Carlo method and so forth have been developed. In comparison with the ab initio MD, the empirical MD can treat a large number of atoms and suits to study the microscopic mechanism of hyper-velocity or instantaneous phenomena such as the collision of space debris into the artificial sattellite and the penetration or spall fracture due to the projectile. It also leads to understanding of macroscopic phenomena. In this study, we adopted the embedded atom method (EAM) potential for the investigation of the behavior of fcc metal (aluminum) subjected to impact loading and especially examined the stress wave propagation problem.
