Abstract

One dimensional shock initiation experiments are reproduced by numerical simulation. The loci of shock wave in explosive obtained by numerical simulation are used to estimate the Hugoniot for high explosive with the same procedure for the experiment. As a result, Hugoniot obtained by this simulation well agrees with the experimental data. Moreover, concept of single curve buildup is investigated numerically. The results indicate that when the shock front is remarkably affected by a reaction wave before the shock front, the locus of the shock front in the high explosive does not pass unique line.
