Simulation and analysis of a 23-mm HEI projectile hydrodynamic ram experiment

An Eulerian wavecode was used to simulate the impact, penetration, and detonation of a 23-mm high-explosive projectile into a water-filled tank. The pressure–time response is compared with results from an experiment conducted by Lundstrom and Andersen ( Symp. on Shock and Wave Propagation, Fluid–Structure Interaction, and Structural Responses, 1989). Computed peak pressures and impulses compare well with the experimental values.
