Daehn Research Group

The Impulse Manufacturing Laboratory (IML) is Professor Glenn Daehn's research group, part of the Department of Materials Science and Engineering at the Ohio State University. For over 20 years, development of novel manufacturing processes has been Prof. Daehn's research focus. The primary focus of IML is impulse-based metalworking, involving high strain rate behavior of materials and driven by pulsed power processes. Current research is largely focused on applications of electrically vaporized foil actuators (VFA), but also includes electromagnetically driven metalworking processes and pulsed laser impact welding. Applications include dissimilar-metal impact welding and conformal interference joining, sheet metal forming and embossing, and powder compaction.
