Biography

Dr. Fatemi received his B.S. and M.S. degrees in structural analysis and design and his Ph.D. in Mechanical Engineering in 1985, all from The University of Iowa. He was on the faculty of Mechanical Engineering at Purdue University-Fort Wayne from 1985 to 1987, and has been on the faculty of Mechanical, Industrial and Manufacturing Engineering at the University of Toledo since 1987. He was promoted to Associate Professor in 1991, and to Professor in 1996. He is currently a Distinguished University Professor.

Dr. Fatemi has taught many subjects in mechanics and design. At the graduate level, he has been teaching courses on fatigue of materials and structures, vehicle structural integrity, fracture mechanics, advanced mechanics of materials, mechanics of composite materials, and experimental mechanics. He has directed theses and dissertations of 50 students at the master and doctoral levels, as well as working with post-doctoral fellows.

Dr. Fatemi's primary research interests and publications involve materials mechanical behavior in general, and in fatigue and fracture mechanics in particular. He has published over 170 refereed papers dealing with 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 has had sponsored research projects with sponsor funding of about $7M from many companies, foundations, and government agencies. Most of these research projects are/were carried out in the Fatigue and Fracture Laboratory at UT. This experimental research laboratory houses state of the art equipment including several servo-hydraulic testing systems.

Dr. Fatemi is a Fellow of the American Society of Mechanical Engineers (ASME), a member of the American Society for Testing and Materials (ASTM) Committee E-8 on Fatigue and Fracture, the Society of Automotive Engineers (SAE) Fatigue Design and Evaluation Committee, and the American Academy of Mechanics.

Dr. Fatemi is on the editorial boards of the International Journal of Fatigue, Theoretical and Applied Fracture Mechanics and the Journal of Advances in Mechanical Engineering. He has received several awards for his research, including the University of Toledo Outstanding Research Award in 2002, and the Sigma Xi/Dion Raftopoulos Award for Outstanding Research in 2008. He has been a member of the Scientific Committee of and a Keynote Speaker at several international conferences on fatigue and fracture.
