Research Interests

One of Dr. Ojard’s interests is experimental characterization of mechanical properties of advanced materials such as ceramic matrix composites and materials for extreme environments. His work focuses on developing new methods to determine key properties that cannot be determined from standard test methods. He develops approaches to utilize non-destructive methods for on-site evaluation of mechanical properties as well as the presence of defects. These are key techniques that need to be developed as materials are considered for aggressive applications such as in gas turbine engines and the next generation of space vehicles.
