    Abstract

    The paper presents a survey of some of the available data on the effects of fatigue in composite laminates. Both static and fatigue behaviors of unidirectional laminae are discussed in terms of the static failure and fatigue limit strains of constituents as well as of loading conditions. Subcritical failure modes in multidirectional laminates are delineated and correlated with the material responses such as temperature increase, modulus change, and fatigue notch sensitivity. Also included are the effects of test frequency and compression. Methods of predicting fatigue strengths of off-axis laminae and of angle-ply laminates are summarized. Finally, two statistical life prediction models are discussed using the material “age.”
