Study on Random Initiation Phenomenon for Sympathetic Detonation of Explosive

It is important to understand the characteristics of explosive sympathetic detonation for explosive safety. Sympathetic reaction test of GHL (RDX/Al/Binder) explosive charges with shell are conducted. A model of the sympathetic reaction test is established. The elements-apart method and nodes random-failure method are used in the model to describe the expansion progress of shell expanding and the randomly forming process of fragments. Random detonation phenomena of acceptor charge are simulated.
