Study on underwater shock wave phenomena in a metallic tube

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 aluminum (AL5052) or stainless steel (SUS304) was used as a closed space. A shock wave was generated in a thick-walled metal tube by detonating a micro-explosive. The process of underwater shock wave interaction with a thick-walled metal tube and the generated shock wave propagation phenomena was simulated by using hydrocode ANSYS AUTODYN. Three underwater shock waves were generated from a thick-walled metal tube. Peak over pressure of shock wave in a stainless-steel tube was higher than in an aluminum tube.
