Professor Shield's research program focuses on understanding the effects that microstructures in modern materials have on the overall behavior of these materials and on their fracture properties. The materials under study include single crystals of shape-memory and other copper-based alloys, as well as novel materials with both magneto-elastic and shape-memory behaviors. Experimental work concentrates on observing the microstructures that form under various types of loading and at the tips of cracks. Single crystals are studied to isolate the microstructural behaviors from the grain-to-grain interactions that occur in polycrystalline materials. Models are then developed that allow the observed microstructures to be predicted and their effects on overall behavior of these materials to be understood. The basic understanding developed by this work will allow the actuators, sensors and other applications that employ these and other similar materials to be improved and designed more reliably. This work is done in collaboration with Professors Leo and James.
