Forming of alloy plate by underwater shock wave of explosive
The fuel cost and efficiency of the automobile greatly depend on the weight. Researches for light weight automotive components are actively being performed, and automobiles using Aluminium alloys instead of steel are becoming more common. However, Al alloys have limited formability in comparison with steel and its final shape is more limited. We have attempted to improve this limited formability of Al alloys by explosive forming technique, which is a particular material processing method. In this method, a shock wave is generated by an explosive and propagated through a suitable pressure medium, e.g. water or air, and deforms a metal plate. We performed numerical analysis using LS-DYNA3D, and compared the results to the experimental observations.
