Abstract
A comprehensive experimental and computational investigation was undertaken
to better understand and predict the mechanisms of damage and failure of metal
tanks filled with liquid after being impacted by a single high-speed projectile.
Impact tests were conducted for a variety of target/projectile orientations and aim
points. The speed of the projectile varied from subsonic, relative to the sound
speed of the liquid fill, to supersonic. The target tanks, composed of steel or
aluminum, were filled with a variety of fluids ranging from Newtonian fluids to
thickened paste. The projectiles were aluminum
