Abstract
This presentation will provide a historical perspective of the development of our understanding of fatigue damage in composite materials. Reviewing the early studies (before 1980) of the damage mechanisms, a conceptual framework for interpretation of fatigue in the form of fatigue life diagrams will be described. Using the diagrams, the roles of fibers, matrix, and fiber-matrix interface in the initiation and progression of fatigue in unidirectional composites will be clarified. Then, the fatigue in multidirectional laminates under uniaxial and multiaxial loading will be discussed. Finally, the process of durability assessment of composite components based on damage mechanics concepts will be outlined.
Speaker
Dr. Ramesh Talreja
Tenneco Professor in the Department of Aerospace Engineering and in the Department of Materials Science and Engineering at Texas A&M University. Prior to that, 1991-2001, he was a professor of aerospace engineering at Georgia Institute of Technology. In 1974 at the Technical University of Denmark he earned his PhD in Solid Mechanics and was endowed with a Doctor of Technical Sciences degree in 1985 on his collected works on fatigue and damage mechanics of composites. Dr. Talreja has written the first-ever monograph on fatigue of composites in 1987 and since then authored 35 books and book chapters, given nearly 300 invited presentations at conferences, universities and industry R&D organizations, taught over 20 short courses, and is or has been on Editorial Boards of 19 international journals as well as has served as Editor-in-Chief of International Journal of Aerospace Engineering and as Associate Editor of Mechanics of Materials journal. His recent work has focused on the effects of manufacturing defects on the performance of advanced composites. He is the recipient of the 2013 ICCM (International Committee on Composite Materials) Scala Award, and World Fellow and Life Member of ICCM. The American Society for Composites selected him for the 2017 Outstanding Researcher Award.
