Fig. 4. Experimental data and fitted lines: (a) shock velocity vs particle velocity; (b) pressure vs density.
Fig. 5. Comparisons between Hugoniot data and models: (a) shock velocity vs particle velocity; (b) pressure vs density. The results of SESAME 7830 and SESAME 7831 are shown as the blue and green lines, respectively, for initial densities of 3.23, 3.36, and 3.515 g/cm3.
