  • The origin, ignition and growth of hot spot are keys to understand the shock initiation in heterogeneous explosive.An experimental method of shock behavior for millimeter-scale plastic-bonded explosives (PBX) is developed by using an electrical explosion driven low-velocity flyer, a quick-response thermocouple and a high speed and micro-scale camera, in which the camera consists of a microscope, a high speed camera and an image transmission bunch.The dynamic collapse process of the precast cavity with a diameter of 0.5 mm in PBX is captured.The physical image and temperature curve of the precast cavity in PBX are obtained during the dynamic collapse process, which may provide a foundation for the hot spots experiment in PBX.
