Dr. McEvily, a professor emeritus of metallurgy, was elected a 2009 Fellow of the International Congress on Fracture (ICF) in recognition of his "contributions to the understanding of fatigue mechanisms and processes in structural alloys." He will be officially honored during the conference of ICF in Ottawa as one of only 52 living Fellows.

Dr. McEvily is recognized across the globe as an authority on fatigue and fracture of metals and alloys. His most important contributions include his 1957 demonstration -- with Walter Illg -- that crack growth rate, da/dN, could be expressed as a function of the parameter KTσ, assuming a crack-like, elliptical, sharp flaw, where KT is the stress concentration factor. Dr. McEvily has also highlighted the importance of cross-slip in fatigue, and has developed various constitutive relations for fatigue crack growth, including overloads and environmental effects.After receiving his D.Sc. from Columbia University in 1959, Dr. McEvily worked as an Aeronautical Research Scientist at NASA in Langley, VA and later served as Head of the Solid State Physics Section. He then worked as a Research Scientist at Ford Motor Company for six years before joining UConn as Head of the Metallurgy Department (67-78). He has authored or co-authored more than 240 papers and two books, including the 2002 textbook, Metal Failures -- Mechanisms, Analysis, Prevention (Wiley-Interscience). Dr. McEvily previously received the Henry Marion Howe Medal of American Society for Metals (ASM) in 1964 and became a Fellow in 1975. In 1983, he was awarded the Nadai Medal from the American Society of Mechanical Engineers (ASME) and was elected a Fellow in 1995. His honors also include the Award of the Mechanics and Materials Division of the Japan Society of Mechanical Engineers (JSME, 1992), Honorary Fellow and Life Member of International Fatigue Congress (1995) and Egleston Medal from the Columbia University (1996). In 2006, the ASM/TMS Mechanical Behavior of Materials Committee sponsored a symposium in honor of Dr. McEvily's 80th birthday, on the subject "Fatigue and Fracture of Traditional and Advanced Materials.
