Ph. D., Theoretical and Applied Mechanics, University of Illinois at Urbana-Champaign
Since 1978, Dr. Socie has held the position of Professor of Mechanical Engineering at the University of Illinois. He is the former Director of the Fracture Control Program, a consortium of ground vehicle companies interested in solutions to fracture and fatigue problems. He has authored over 150 technical articles on all aspects of fatigue and durability assessment techniques including the ASTM standard E1049 on cycle counting methods. The Wöhler Medal from the European Structural Integrity Society, Award of Merit from American Society for Testing and Materials and the Colwell Award from the Society of Automotive Engineers are amoung his many awards. Dr. Socie is an invited lecturer throughout the United States, Europe, China and Japan. He has been teaching industrial fatigue seminars for over 30 years. He has been active in small business development and is one of the founders of SoMat.
M.S. and Ph. D., Theoretical and Applied Mechanics, University of Illinois at Urbana-Champaign
Professor Sehitoglu holds the John, Alice, and Sarah Nyquist Endowed Chair ot the University of Illinois. Professor Sehitoglu has more than 150 publications that have significantly advanced scholarship related to thermomechanical fatigue, fatigue crack closure, stress-induced phase transformations, cyclic ratcheting plasticity, slip and twinning in metals. He is the current Director of the Fracture Control Program and Editor of the ASME Journal of Engineering Materials and Technology.
Ph. D., Mechanical Engineering, University of Illinois at Urbana-Champaign
Dr. Downing has more than 35 years of experience in fatigue analysis and product testing. As a research engineer at Deere & Co., he was responsible for most of the corporate fatigue prediction software used by the engineering centers. At SoMat Corporation, he was involved in hardware and software development, marketing, and customer training. He has made significant contributions in the area of cast iron fatigue prediction, cycle-counting methods, and field data analysis. He is currently Lecturer and Adjunct Associate Professor of Mechanical Engineering at the University of Illinois.
Ph. D., Mechanical Engineering, University of Iowa
Professor Fatemi has been on the faculty of Mechanical, Industrial and Manufacturing Engineering at the University of Toledo since 1987. He has been teaching classes on fatigue of materials and structures, vehicle structural integrity, and fracture mechanics. Professor Fatemi has authored more than 120 publications on fatigue and fracture, both at the basic level helping to understand fundamental fatigue damage mechanisms, as well as in the applied areas facilitating applications of the knowledge learned to the design and life prediction of engineering components and structures. He has co-authored the second edition of a fatigue textbook entitled "Metal Fatigue in Engineering" published by Wiley in 2000. He is a member of ASTM Committee E-8 on Fatigue and Fracture, and the SAE Fatigue Design and Evaluation Committee.
Ph.D., Mechanical Engineering, University of Kyushu
Professor Hashimura is an associate professor of Mechanical Engineering at Kurume National College of Technology. He has industrial experience at Mitsubishi Heavy Industries for two years before joining the university. He has been researching the strength of bolted joints including the bolt tightening method for 15 years. Professor Hashimura is a member of JSME Machine Design & Tribology Division committee.
