Control/Mechanics/Materials

Links the expertise of dynamics and control, mechanics, materials, tribology, and surface engineering. Research is directed toward understanding deformation, fatigue, fracture, and corrosion of all classes of materials, including composites, to account for the underlying microstructural state and its origin, transformation, and evolution. Typical areas include development of a quantitative description of critical microstructure through mesostructural features; relation to macro-mechanical properties; constitutive models and their experimental verification; smart materials; effect of surface, near-surface, and interface material on the performance of mechanical components and structures that are subject to tribological conditions; and mechanical and thermal stresses and environmental degradation. A broad range of topics are supported including research on newly-engineered surfaces for optimal topography and microstructure that will lead to improved tribological materials, lubricants, and coatings for operation under severe conditions; and dynamic behavior and control of machines, processes, structures, and other engineered physical systems, thus emphasizing an improved knowledge-base for understanding their performance and control.
