Abstract : Hydraulic ram concerns catastrophic failure of liquid filled tanks impacted by high speed projectiles. It is divided into four phases: entry/shock, pressure field, cavity, and free surface. The entry wall phase was investigated in detail. A formula to predict energy losses of a bullet penetrating an aluminum plate is presented, and experimental data were obtained and compared. A fiber optic transducer wad designed to measure generated pressures in the shock and cavity phases. (Author)
