Tungsten bead fragment is composed of high performance explosive and tungsten bead shell. Explosive explosion produces detonation wave and a large number of detonation gas under high temperature and high pressure, these impact on the tungsten pearl shell and cause huge deformation until it breaks.
After crushing, tungsten pearl shell will form fragments with divergent distribution. The detonation product formed by explosive explosion will escape, and the fragments formed by the metal shell will be immediately surrounded. The fragment is accelerated by detonation waves and high temperature and pressure gases until the gas expands at a rate lower than that of the fragment. Because the detonation wave attenuates is faster than the fragment velocity attenuation, after a short time, the fragment will fly out of the detonation product surrounding. Therefore, the impact distance of broken pieces is larger than that of shock wave.
