摘要：
A particular characteristic of an explosively produced weld is that the profile of the weld interface often has a regular wavy appearance. Effects of detached shock wave and jetting on the metal interface of explosive welding has been considered by SPH. Numerical results show wavy interface which is observed in several experiments. A high speed jet between interface and Karman vortex after oblique impact of a flyer plate to a parent plate were major mechanism of explosive welding.
