Coherency for the critical condition of DDT and SDT in energetic materials

With safety issues playing a dominant role in prese nt-day energetic materials technology, concern is i ncreasing about the relative safety of solid high explosives shocked initiation(SDT) and deflagration to detonat ion transition (DDT). The critical conditions and parameters have been measured about SDT and DDT, the results indica te that existence coherency apparently between the critical initiation of SDT and DDT in this paper. Some of t he results such as the increase velocity of combustion peak, tscope and the movement velocity in SDT i ndicated its existence.
