Abstract

The loading and unloading paths of shock impact on granular metal were analyzed, and the attenuation of planar explosion shock wave in granular metal was investigated using characteristic method. The results showed that the initial peak pressure of the shock wave was determined by the type and property of the metal, porosity and detonation velocity of the explosive. The higher of impact impedance and porosity of metal and higher the detonation velocity were, the higher initial peak pressure was. The attenuation was determined by the length of explosive, impact impedance and porosity of the metal. The higher of impact impedance and porosity of metal and shorter explosive cylinder was, the more quickly the shock wave attenuated.
