Research

Prof. Lucas' expertise is in the experimental evaluation of mechanical properties of advanced structural materials, and how these properties change in response to microstructural changes induced by processing or service environment (chemical, thermal, or nuclear). His current interests include fracture and stability phenomena in composite materials, novel techniques to extract mechanical properties from small volume specimens, and fracture mechanisms in structural steels used in advanced energy systems.
