Abstract:
A new emulsion explosive was obtained by introducing energetic microballoons containing alkane into emulsion matrix. Energetic microballoons were foamed in a constant temperature environment of 90 ℃ for 5 min to reach the maximum volume, and then ene...

Abstract:
Metal spallation phenomenon often occurs when shock waves are reflected and unloaded on a free surface. If there is a secondary shock wave impact, the metal spallation zone will be compressed again, and the metal in the tensile state will be graduall...
