Stress Analysis on Projectiles Colliding into Sand
In a cannonball firing test, inactive cannonballs are fired to an impact area of a medium such as sand. Collision, penetration, impulse damping and fracture are investigated. For an efficient construction and utilization, researches on media for an impact area are necessary. In this study, the collision and penetration of cannonballs into sand is analyzed. It is found that density of a medium is an important factor.
