This website contains a wide variety of web based fatigue analysis software tools for computing fatigue lives of metallic machine components and structures. The technologes contained in this website are the result of the collective expertise of many people. Here are some of the major contributors to eFatigue. We would also like to acknowledge our colleagues who have contributed material property data and source code and wish to remain anonymous.

Darrell Socie

Ph. D., Theoretical and Applied Mechanics, University of Illinois at Urbana-Champaign
B.S. and M.S. Metallurgical Engineering, University of Cincinnati

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.
