The explosive forming is one of the forming methods of metal plates has been performed since 1950. This method is different from usual static press forming. The metal plate is accelerated by underwater shock wave, which is generated by underwater explosion of an explosive. We have tried the experiment of aluminum alloy forming using this method. In this research, a forming limit for aluminum alloy has been clarified from the experimental results. Then, we have tried the numerical simulation for this method using finite difference method. In this research, two methods for forming aluminum plates using closed metal vessel and paper vessel are introduced and the results of numerical simulations corresponding to those experimental conditions are shown.
