Abstract
The double card gap tests of explosives were conducted. In the tests, the delayed detonations (XDT) of JO-9159 explosives were recorded with an X-ray camera. The numerical simulations of the detonation tests were performed. Both the experimental and the calculation results show that the detonation times of XDT are random and delayed by more than 10 μs compared to the standard shock to detonation transition. The repetitive loading conditions by shocks and the sensitization levels of the explosives under shock loading are the main concerns for controlling the delayed detonation.
