The focus of our research in the Deformation Processes
Laboratory is on quantifying our understanding of the
link between the structure of engineering materials and
their performance in design applications. Our work
includes the development of both experimental and simulation
techniques, with special attention to coordinating the
two to best reach our objectives.
We work primarily on polyphase engineering alloys that
have application as structural materials in airframes,
ships, automobiles and engines. Critical properties, ranging
from stiffness to strength to failure, stem from the crystalline
structure of these alloys. Establishing a quantitative
connection between the structural features at this scale
and the macroscopic properties is vital to most effectively
Our methodologies attempt to build these connections.
We also apply our simulation and experimental tools to several forming processes. Structural alterations can be the intended outcome of processing or can be the inevitable result of processes carried out for other reasons. In either case, processing is a key element in modifying the structure that eventually determines properties. We have been developing methods for analyzing the thermomechanical histories in bulk forming and sheet forming processes. In addition we are particularly interested in solid state joining processes, such as friction stir welding, where the combined influences of high temperature and severe deformation provide major challenges for our tools.
