Experimental Studies on the Overdviven Detonation Events in Condensed Explosives

Maximum detonation pressure of 2.5 times than its C-J value was obtained in TNT/RDX (40/60) by using planar flyer impact technique. The equation of state of overdriven detonation product was derived as the form of p=Ak+A1(p-pJ) (p－detonation pressure, GPa, －density, kg/m3, A=J/kJ, pJ=27.06 GPa, J=2.3103 kg/m3, k=2.77, A1=2.710-3 GPa-1). The reflected shock state of the overdriven detonation product could be also described by the above equation satisfactorily.
