Abstract
The impact of high-velocity projectile on fluid-filled containers can cause hydrodynamic ram (HRAM) events. When multiple projectiles impact, HRAM effect is superimposed. In this paper, we presented the experimental results of cavity dynamic, pressure-time histories, and impulse-time histories caused by single and double projectiles impacting water-filled containers.
