Abstract
As a new method of generating the overdriven detonation, the concentric double cylindrical high explosive was developed. From the results of a numerical analysis, a measurement of a detonation velocity and a detonation pressure, it has been inferred that the detonation velocity and the detonation pressure was about two times higher than that of the Chapman-Jouguet state. In this investigation, as a application which used the super high energy obtained by the overdriven detonation, the experiment of the shock consolidation of a metallic powder was done. A metallic powder used the tungsten carbide with high hardness and a high melting point. As a result of the shock consolidation experiment, the tungsten carbide had been solidified though the crack was slightly generated. From the condition of Prummer and Meyers, it was inferred that the shock pressure that was more than 21GPa was load with the tungsten carbide powder. The effectiveness of the concentric double cylindrical high explosive could be also shown for the shock consolidation system in this investigation.
