Molecular Dynamics Analysis of Damage Process of Al or Ni Metallic Multilayer and monolayer Structures by HVI

Abstract

Hypervelocity impact (HVI) of metallic projectile on Al or Ni multilayer composite structure or monolayer structure are simulated by molecular dynamics (MD) method with the relative velocity up to 14,000 m/s,. The translational kinetic energy of the projectile causes the formation of heat and the deformation of solid bodies. Damage, deformation and phase transformation of the solid bodies are analyzed from the mesoscopic viewpoint. The space distribution of physical quantities in the both structures in collision process are visualized by CG movie.
