Al・Ni多層構造ならびに単層構造のHVIによる損傷過程の分子動力学解析

抄録

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.
