Hypervelocity impacts (HVI) of metallic projectile on Al single crystal are simulated by molecular dynamics (MD) method. The relative velocity between two bodies is 7,000, 10,000 or 14,000 m/s at the collision. 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 is analyzed as local value by using voxel defined by cylindrical coordinates. Number density, temperature, center of mass and velocity of center of mass of the voxels are calculated. Deformation and fracture process are visualized by CG movie.
