A study of the overdriven behaviors of PBX 9501 and PBX 9502

PDF Version Also Available for Download.

Description

The author presents the Hugoniot pressure and sound speed data in the overdriven regime for both PBX 9501 and PBX 9502. The overdriven release experiments are also given. The failure of the standard Jones-Wilkins-Lee equation of state in modeling both the Hugoniot data and the overdriven release experiments for both high explosives are identified and remedy is made by including additional terms to steepen the slope of the Hugoniot in the high pressure regime. However, an anomaly presented itself as a kink in the release wave of PBX 9502 is observed. A careful examination of the Hugoniot data indicates similar ... continued below

The author presents the Hugoniot pressure and sound speed data in the overdriven regime for both PBX 9501 and PBX 9502. The overdriven release experiments are also given. The failure of the standard Jones-Wilkins-Lee equation of state in modeling both the Hugoniot data and the overdriven release experiments for both high explosives are identified and remedy is made by including additional terms to steepen the slope of the Hugoniot in the high pressure regime. However, an anomaly presented itself as a kink in the release wave of PBX 9502 is observed. A careful examination of the Hugoniot data indicates similar behavior. A possible explanation is suggested for this peculiarity to the phase transition of carbon in the products.
