ABSTRACT
The underwater shock wave initiation and propagation were visualized by the high speed image converter and high speed color video camera and the pressure transitions was measured by using the tourmaline sensor method. The shock wave pressures produced by the explosive and the electric pulse energy were measured and the optimum crushing conditions were discussed. The pressure variation under underwater shock wave which is caused by these energies was measured. The chapter discusses the raw material recycling of glass container crushing technique by the explosive and the largest electric pulse energy. The explosive used was PETN and an electric detonator was used as an igniter. A pressure sensor and an explosive are set in the support frame. The shock wave propagation, glass fracture behaviors by shockwave and shockwave pressure change produced by the explosive and the electric pulse energy were observed and measured.
