The shock forming method is one of the material processing methods. In this method, the shock wave generated by the explosion and propagated through a suitable pressure medium like as a water or air act on a metal plate, a metal tube, etc. It gives a very high strain deformation of the material and finally a suitable plastic deformation. This method is called as a shock bulge forming. The advantages of this method are hard to produce the spring back and a high strain rate material processing. The material processing at high strain rate leads an extreme high deformability of the aluminum base alloys. The predominance of shock bulge forming is investigated by comparing with static press bulge forming.
