Title: A combined experimental and numerical investigation on projectiles penetrating into water-filled container
Abstract: The experiments and numerical simulations of projectile penetrating into water-filled container with aluminum target plates were conducted. The motion of projectile and cavity evolution of hydrodynamic ram in water were assessed. The results show the propagation characteristics of initial shock wave of hydrodynamic ram in the container. The study presents that the plugging with outward deformation was the main failure mode of the target plates when the velocity of projectile was below 270 m/s. With the velocity of projectile increasing, the ultimate deformation of plates increased linearly and the petaling failure appeared on the rear plates. Four kinds of typical failure modes for plates of water-filled container were concluded through the combining results of experiment and simulation. In addition, the effect of plate thickness on the plastic deformation were discussed, and the quantitative relation among the deformation of target plates, velocity of projectile and plate thickness were established.
