Frank Kraft has held engineering positions in government, specifically the Department of the Army, and in industry. Prior to joining the mechanical engineering faculty, he was the research and development manager for the extruded products division of Brazeway, Inc., a worldwide leader of extrusion products and refrigeration components for the heat transfer, automotive, appliance, and commercial refrigeration industries.


Research Interests: hot extrusion of copper hollow profiles, extrusion of a copper/carbon nano-tube composite material into high conductivity wire, mechanical behavior of precision single and multi-channel tube for advanced climate control systems, development of flow stress data and constitutive equations for metal forming
