NUMERICAL SIMULATION OF EXPLOSIVE FORMING

摘要: Explosive forming is one of the unconventional techniques, in which, most com- monly, water used as pressure transmission medium. The explosive set at top vessel filled with water, and detonated by an electric detonator. underwater shock wave propagates through medium impinges on metal plate, which turn, deforms. There another pulse acting plate secondary product expansion gas generated detonation explosive. duration longer peak lower than primary pressure. However, intensity these based also conditions a vessel. In order to understand influence configuration deformation numerical analysis was performed. This paper reports those results.
