Abstract
This paper reports numerical results underwater shock wave generation phenomena by an explosion in a closed space for establishment of shock wave pressure profile method related to the shock wave medical and biomedical application. In this study, a metal tube made of stainless steel were used as a closed space. A shock wave generated in a metal tube by detonating a micro-explosive (a 10 mg silver azide pellet). The process of underwater shock wave interaction with a metal tube and the generated shock wave propagation phenomena was simulated by using hydrocode ANSYS AUTODYN. The peak over pressure of shock wave generated form a metal tube was higher by different internal shape.
