Measurement of Hugoniot Relation for JB-9014 Insensitive Explosive

In this paper we measured the Hugoniot data for JB-9014 explosive by measuring the times when the shock wave reached the surfaces of the explosive sample and the particle velocity at the sample/window interface on a gun using PDV.Calculating the difference between the times when the shock wave reaches the front and the back surfaces of the sample explosive and its thickness, we figured out the propagation velocity of the shockwave in the sample, and found that the combined standard uncertainties of the shock velocity and the particle velocity were 0.54% and 1.7% within the pressure range of 3.1-9.7 GPa, through uncertainty analysis.Moreover, we also derived the relation between the pressure and the density of the JB-9014 explosive sample from the simultaneous equation of the Hugoniot relation and the Rankine-Hugoniot relationship of the shock wave form and obtained the fitted p-ρ curve in the sample along the (p, ρ) surface under heat-insulated shock.
