Thus hollow profiles can be compressed or expanded and flat or three-dimensionally preformed sheet metal can be shaped and joined as well as cutting operations can be performed. Due to extremely high velocities and strain rates in comparison to conventional quasistatic processes, forming limits can be extended for several materials. In this article, the state of the art of electromagnetic forming is reviewed considering: Article history: Received 10 September 2010 Received in revised form 7 December 2010 Accepted 15 December 2010 Available online 23 December 2010 Keywords: Electromagnetic forming Impulse forming High-speed forming • basic research...
