Abstract


In detonation of an explosive, there are two forms, high velocity detonation(HVD) and low velocity detonation (LVD). For example, it is known that thedetonation velocities of methyl nitrate are 6700m/s in HVD and 2500m/s inLVD. In a liquid explosive, the highest pressure of LVD changes with thetype of explosive and conditions, is a few GPa and has destructive powerequivalent to HVD. It is important also for security to get to know the actualcondition of LVD. Moreover, it is important that the performance ofexplosives is completely understood to control HVD, LVD, and deflagration,and to predict the behavior of the explosive.
