Sand Behavior Induced by High-Speed Penetration of Projectile. Phenomenological studies of the response of granular and geological media to high-speed (Mach 1-5) projectiles

摘要

This is the final report of a project to grasp various phenomena induced by the high-speed impact of projectiles on sand. These were the behavior of ejecta and the projectile, the penetration depth and speed of the projectile, and fractured grains and pressure distribution.
