Abstract

Impulse based metalworking has significant advantages, in that short time scales change the fundamental nature of the forming process and short duration impulses can be used with much lighter and more agile equipment because large static forces do not need to be resisted. Electrically vaporized thin conductors, termed as Vaporizing Foil Actuators (VFA), can be used to develop significantly high driving pressures over short time scales. The driving pressures can be a few GPa’s, and have been used to launch sheet metal workpieces to velocities in excess of 1 km/s. Applications include, but are not limited to, impact welding, forming, embossing, shearing, tube joining, and powder compaction.
