Effect of Material Phase Change on Penetration and Shock Waves
Abstract
This paper has presented computed results that investigated the effect a material phase change, and strength, had on penetration and shock waves. Three phase change conditions and three levels of material strength were used. The results showed that penetration was very sensitive to the level of material strength and less sensitive to the phase change pressure. The shock wave response showed more sensitivity to the phase change condition and less sensitivity to the level of strength. More importantly, the results demonstrated that when a volume loss phase change occurs, it produces a softer material response, which reduces the material resistance. The effectiveness of an armor material depends on many of its characteristics. It appears from this work that the presence of a volume loss phase change reduces the ballistic efficiency of the material.
