Abstract
considered a projectile penetrating a box which contains water either partially or fully. A standard model was developed and validated against the experimental data. Then, each parameter was varied individually to determine its effect during the HRAM event. The parameters considered were the water filling level in the box, its wall thickness, projectile impact velocity, projectile mass, impact angle, and projectile shape. The effect of individual parameter was compared, and the effects of different parameters were compared. Then an attempt was made to determine the combined effects of multi-variables. Even though the results and discussion are for the specific geometric and material data used in this study, the present findings are expected to provide valuable insights to the qualitative characteristics on the HRAM event.

    Ball motion in a ball-obturated tubular projectile 

    Nunn, Robert H.; Bloomer, James Wayne (Monterey, California. Naval Postgraduate School, 1981-01); NPS69-81-001B
    When a ball with a concentric hole through it is suspended within a spinning tubular projectile the ball will rotate in such a way that its hole is aligned with the axis of spin of the projectile. The ball thus serves as ...

    Simulation of hydrodynamic ram phenomenon using MSC Dytran 

    Yang, Kangjie Roy (Monterey, California: Naval Postgraduate School, 2014-09);
    Hydrodynamic ram (HRAM) refers to the damage process due to high pressures generated when a high-velocity projectile penetrates a compartment or vessel containing a fluid. A Finite Element model was developed using MSC ...
