Unreacted Hugoniots for porous and liquid explosives
- Los Alamos National Laboratory, Group M-7, MS P952 (United States)
Numerous authors have measured the Hugoniots of a variety of granular explosives pressured to different densities. Each explosive at each density was typically then treated as a unique material having its own Hugoniot. By combining methods used by Hayes, Sheffield, and Mitchell (for describing the Hugoniot of HNS at various densities) with Hermann's [ital P]-[alpha] model, it is only necessary to know some thermodynamic constants or the Hugoniot of the initially soild material and the porous material sound speed to obtain accurate unreacted Hugoniots of the initially solid material and the porous material sound speed to obtain accurate unreacted Hugoniots for the porous explosive. We discuss application of this method to several materials including HMX, PETN, TNT, and Tetryl, as well as HNS. We also show that the Universal Liquid Hugoniot'' can be used to calculate the unreacted Hugoniot for liquid explosives. With this method only the ambient pressure sound speed and density are needed to predict the Hugoniot. Applications presented include nitromethane and liquid TNT.
