Research Areas

General technical interests deal with assuring the safe operation of aerospace and other complex structures through damage tolerance analyses and nondestructive inspection. Particular emphasis is on basic research to predict critical and subcritical crack growth under static and cyclic loads (i.e. fracture and fatigue). The influence of corrosion on structural integrity is also of interest. This research employs numerical and experimental approaches, and impacts both the design of new components as well as the continued operation of older structures (i.e. aging aircraft).

Experimental research is conducted in the School of Aeronautics Fatigue and Fracture Laboratory. This facility has two computer-controlled electro-hydraulic test machines and associated equipment needed to measure fatigue crack formation, propagation, and fracture in specimens subjected to simulated aircraft or spacecraft load histories. A scanning electron microscope is on hand to examine fracture surfaces and equipment are also available to artificially corrode specimens in connection with corrosion and/or corrosion-fatigue related research.
