Abstract

Abstract

An embedded electromagnetic particle-velocity gauge was used to measure the shock initiation behavior in JOB-9003 explosive under different shock pressures. The particle velocity history profiles can fairly decribe the change processes from the shock waves to the detonation waves in the explosive. The output signal from a shock tracker shows that at the shock pressures of 4.9 GPa and 58 GPa, the critical times and distances for the onset of detonation of JOB-9003 explosive are respectively 6.06 mm and 1.13 s , 5.66 mm and 1.01 s.
