Description
Abstract:	An unsteady, hydrodynamic model of the impact of a low strength projectile on a rigid or semi-rigid target has been developed. Impact tests of various materials including birds, gelatin, and RTV rubber have been conducted to validate this theory. At velocities above 100 m/s, these materials were seen to flow as a fluid upon impact. The resulting impact pressure histories were very similar to those predicted using the model. The impact process was dominated by an initial shock phase which was quickly followed by a release to a steady flow condition. This model should be applicable to the impact of any material for which the shock pressures generated during impact are much greater than the strength of the projectile but are less than the strength of the target.
