This paper is concerned with the understanding, interpretation, and engineering representation of fatigue damage development in continuous-fiber composite laminates that are fiber dominated, but have significant effects caused by damage in the off-axis plies. It is the objective of this paper to present a description of damage development under tension-tension, tension-compression, and compression-compression cyclic loading that is as complete and generic as possible in the sense that it can be used as a basis for engineering representations and interpretations of the effect of such damage on the strength, stiffness, and life of composite laminates.
