Introduction to Thermodynamics of Mechanical Fatigue

Michael Khonsari is the holder of the Dow Chemical Endowed Chair and Professor of the Mechanical Engineering Department at Louisiana State University where he directs the Center for Rotating Machinery (CeRoM). Professor Khonsari is a fellow of ASME, STLE, and the American Association for the Advancement of Science (AAAS). He holds several patents and he has authored two books and over 240 archival journal articles, book chapters, and special publications. He is currently the chief editor of the ASME Journal of Tribology. Mehdi Amiri earned his Ph.D. in mechanical engineering from Louisiana State University where he is currently a research associate in the Center for Rotating Machinery (CeRoM). His area of research is in the field of fatigue and fracture analysis. He holds one patent and has authored several journal publications. His research interests include thermal/fluid mechanics, thermodynamics, tribology, and failure analysis.
