M.-H. Herman Shen has been a professor of Mechanical and Aerospace Engineering at the The Ohio State University since 1989. He received his M.S. and Ph.D. degrees in Aerospace Engineering from The University of Michigan in 1986 and 1989, respectively. He joined the faculty of the Aerospace Engineering at The Ohio State University in August 1989. Other experiences include appointments as a Visiting Scholar at University of Tokyo in 1997, a Senior Visiting Scientist at the AFRL (the Air Force Research Labs) in 2000, and a Visiting Scholar at Institut de Genie Atomique, Lausanne, Switzerland in 1999.
For the past twenty years, Dr. Shen has been active in research of the structural analysis/design and manufacturing methods in a variety of subjects ranging from developing lighter, stronger, and more durable structures of aircraft and automobiles to manufacturing process reliability, maintainability, quality improvement, material characterization, thermo-mechanical failure assesments. Over the last ten years, he has pioneered developments in fatigue life prediction schemes for gas turbine engine blading systems, advanced composites, and adhesive joints. He is now heading several major research programs on high cycle fatigue aimed at developing a damage tolerant design methodology. Prof. Herman Shen authored or co-authored more than 100 refereed journal, proceedings papers and book chapters.
