Ting Zhu

Woodruff Professor, Woodruff School of Mechanical Engineering

Zhu's research focuses on the modeling and simulation of mechanical behavior of materials at the nano- to macroscale. Some of the scientific questions he is working to answer include understanding how materials fail due to the combined mechanical and chemical effects, what are the atomistic mechanisms governing the brittle to ductile transition in crystals, why the introduction of nano-sized twins can significantly increase the rate sensitivity of nano-crystals, and how domain structures affect the reliability of ferroelectric ceramics and thin films. To address these problems, which involve multiple length and time scales, he has used a variety of modeling techniques, such as molecular dynamics simulation, reaction pathway sampling, and the inter-atomic potential finite-element method. The goal of his research is to make materials modeling predictive enough to help design new materials with improved performance and reliability.

    Jeffrey Streator

    Associate Professor, Woodruff School of Mechanical Engineering

    Streator’s research is concerned with the interactions between contacting surfaces, with particular emphasis on the roles played by surface roughness and by intervening liquid films. Much of this research is motivated by problems of adhesion or “stiction” that is prevalent in small-scale devices such as microelectromechanical systems (MEMS) and in the head-disk interface of computer disk drives. As device form factors continue to shrink the role of surface forces, such as liquid surface tension become increasingly dominant as compared to inertial forces. In this regard Streator has been interested in developing models that consider the interplay between liquid-drive capillary stresses and elastic restoring forces. This work has led to models of contact instabilities force generation predictions for both smooth and rough interfaces.

    Neu's research involves the understanding and prediction of the fatigue behavior of materials and closely related topics, typically when the material must resist degradation and failure in harsh environments. Specifically, he has published in areas involving thermomechanical fatigue, fretting fatigue, creep and environmental effects, viscoplastic deformation and damage development, and related constitutive and finite-element modeling with a particular emphasis on the role of the materials microstructure on the physical deformation and degradation processes. He has investigated a broad range of structural materials including steels, titanium alloys, nickel-base superalloys, metal matrix composites, molybdenum alloys, high entropy alloys, medical device materials, and solder alloys used in electronic packaging. His research has widespread applications in aerospace, surface transportation, power generation, machinery components, medical devices, and electronic packaging. His work involves the prediction of the long-term reliability of components operating in extreme environments such as the hot section of a gas turbine system for propulsion or energy generation. His research is funded by some of these industries as well as government funding agencies.

    Professor, Woodruff School of Mechanical Engineering

    Green’s research has been conducted under industrial and government sponsorship. His work broadly supports the field of design, rotordynamics, and tribology. The calculation of stiffness of bolted joints has become standard in classical design textbooks*. In 2006 he received the ASME highest honor, the Machine Design Award. His work on the dynamic behavior of mechanical seals operating in liquid or gas (again award winning) has been implemented into various computer codes which have been acquired by seals manufacturers, users, and research labs. For two decades he taught two continuing education courses: (1) The “Mechanical Engineering Professional Engineering Refresher,” and (2) with colleagues from BHRG, he taught and administered the course “Fluid Sealing Technology.” He served on numerous editorial boards, served on the STLE Board of Directors, and chaired two terms the Executive Committee of the ASME, Tribology Division.
