Abstract

The detonic people know that the detonation waves need some minimum radius to turn the detonation direction for 90 degrees and much more to come from a forward detonation in a rearward detonation or retonation. Most of the corresponding tests can distinguish between the build-up distance and the necessary minimum radius. The retonation behavior is generally tested with tubular charges where the minimum wall thickness is determined at which a forward detonation converts also into a retonation. A new method with the help of multiple flash gap technique was tried in which the corner turning distance and the retonation behavior or the necessary minimum explosive layer thickness should be defined with 'one' test only.
