Effect of Material Phase Change on Penetration and Shock Waves

Abstract

This paper presents computed results that investigate the effect a material phase change has on penetration and shock waves. The effect of material strength is also presented for comparison. Three phase change conditions are used to investigate the phase change effect, and three levels of material strength are used to investigate the effect of strength. The results show that the shock wave response is very sensitive to the phase change condition and less sensitive to the strength. The penetration results show that the depth of penetration is very sensitive to the level of material strength and less sensitive to the phase change condition. The results also demonstrate that a phase change (resulting in a volume loss) produces a softer material response, which results in more penetration.
