Hypervelocity-Impact Shock-Induced Damage to Steel Armor

Abstract

The object of this research was to develop the physics of hypervelocity-impact induced spallation to the extent that small 1-g projectiles can be designed to optimize backface spall in steel armor. Over 100 successful impact experiments and their metallurgical analysis were completed. Some preliminary heuristic spallation theory was developed. The importance of the 130-kbar phase change and adiabatic shear in martensitic steel is discussed. A preliminary conclusion is that such projectiles can be designed; however, more research is needed for optimization.
