Department Chair, Mechanical Engineering–Engineering Mechanics
Professor, Mechanical Engineering–Engineering Mechanics
- PhD, Engineering Mechanics, Iowa State University
- MS, Engineering Mechanics, Iowa State University
- BS, Engineering Science, University of Notre Dame
Dr. Predebon's research includes mechanical behavior, characterization and processing of ceramics, shock deformation including microstructural effects and dynamic fracture of metals and ceramics, impact phenomena, computer simulation of wave phenomena, explosive-metal interaction and fragmentation. His research usually involves experimental, analytical, and computational elements.
Dr. Predebon's research in mechanical behavior and processing of alumina has recently resulted in two patents. This newly developed alumina has exceptional compressive and tensile strength properties which increase with strain rate. It has also increased toughness. It has an enhanced dynamic yield strength (Hugoniot Elastic Limit) and spall strength. Potential applications being considered are ceramic cutting tools, engine components (pistons, valves, etc.), bioceramics, electronic structures, and armor.
