This presentation will discuss fundamental considerations in fatigue of composite materials with fibrous reinforcement. General concepts underlying irreversibility in stress-strain behavior
will be addressed and the associated dissipative mechanisms will be discussed. A conceptual framework for interpretation of the roles of fibers, matrix and fiber/matrix interface, introduced
by the author in a 1981 paper, will be described. The extension and variation of the baseline framework, called the fatigue life diagram, to general cases of loading and fiber architecture
will be treated. Finally, guidelines will be offered for modeling changes in materials response and consequent loss of functionality under different fatigue conditions.
Professor Ramesh Talreja is currently Tenneco Endowed Professor in the Department of Aerospace Engineering at Texas A&M University. Prior to that, 1991-2001, he was a professor
of aerospace engineering at Georgia Institute of Technology. His early research career was at The Technical University of Denmark, where he received his PhD (1974) and
Doctor of Technical Sciences (1985). Prof. Talreja has published extensively in the composite materials field, including a monograph, Fatigue of Composite Materials (1987),
Damage Mechanics of Composite Materials (editor, 1994), Polymer Matrix Composites (editor, 2000), and his latest book, Damage and Failure of Composite Materials
(with C.V. Singh, Cambridge University Press, 2012). He has written 25 book chapters, given over 230 invited presentations at conferences, universities and industry R&D
organizations, taught over 20 short courses, and is or has been on Editorial Boards of 15 international journals. He is the recipient of the 2013 ICCM Scala Award and World
Fellow and Life Member of ICCM. His current interests are in cost-effective and sustainable design of composite structures.
