Abstract: The evolution of the material density profile behind the front of a divergent initiating shock wave in HMX and RDX based explosives in the transitional regime of explosive transformation was studied using flash radiography. The explosives were loaded by a divergent shock wave through a Plexiglas layer of varied thickness. Distinctive features were found in the evolution of the density profile behind the front of a divergent initiating shock wave that did not become a detonation wave and behind the front of an initiating shock wave that became a detonation wave.

Keywords: explosive, initiating shock wave, detonation, flash radiography, material-density distribution.
