Abstract

The paper develops a model for evaluating results of high velocity fragment or bullet interaction with thin walled fluid-filled containments. 
The closed form solution formulas for determining wall perforation conditions, or crater depth, radius and ejected mass being functions of impactor mass, speed and material of both impactor and target are provided. The dynamics of impactor deceleration after wall perforation of the fluid filled containment was studied being the function of the depth of perforation under the water level in case the containment was partially filled with water and partially with gas having a distinct fluid-gas interface. Approximation formulas were developed making it possible to simulate resistance and drag forces being functions of governing parameters. The resistance and lift forces strongly depend on the depth of body motion under free surface. Due to that reason the response of containment on high velocity perforation depends on amount of fluid.
The developed models are verified with results of experiments. The obtained solutions are applicable for evaluation of the consequences of high velocity impact of Space debris elements on different space structures, and developing concepts for effective shields design.
