Abstract

The study summarizes experiments and theoretical investigations to explore the behavior of liquid filled containers under medium speed impact. Thin-walled cylindrical steel containers with different wall thickness were impacted by gun projectiles. To investigate the major difference of the container failure modes empty and water filled containers were used. In the case of the water filled containers the impact damages ranged from simple perforation of front and rear wall to a catastrophic front wall rupture which started at the rim of the impact hole and an additional perforation of the rear wall. The development of the pressure distribution in the water starting at the point of penetration was followed through the container to the opposite wall and back to the point of entry of the projectile.
