What Is Fatigue Damage?

Source

A conceptual definition of fatigue damage is proposed to assist in the selection of measurement techniques and parameters for correlating damage with fatigue life. To illustrate the concept, a critical review of some typical damage parameters for composite materials is given. A survey of some new techniques for damage monitoring, including the small angle neutron scattering (SANS) method, is presented and discussed. Pitfalls in damage modeling are illustrated with examples drawn from the literature. A summary of an ASTM E9.01 panel study on fatigue damage and research opportunities in the 1980's is presented.
