Analysis Of High Speed Framing Camera Data For The Development Of Material Models Used In Penetration Mechanics.

Abstract

The results of penetrator and target interaction is an interesting and important area of science. To aid designers of armor and armor penetrators, analytical tools have been developed to describe the results of penetration events. The success of the analytical model is dependent on the ability to accurately describe the material response under dynamic conditions found in the penetration process. This paper describes the use of high speed framing camera photography for the development of material behavior models. One test to characterize material behavior under dynamic conditions is the cylinder impact (or Taylor) test.1 Shadowgraphic photography of the impact event at very high framing rates provides investigators with time resolved data needed for experimental characterization of material behavior.2'3 Results from this investigation have been used in the development,.of new theories which provide analytical description of the cylinder impact test.'
