Remaining-Life Assessment of Fatigued Metals
Numerous studies on fatigue of metals have been published. As summarized in some monographs (Klesnil and Lukas, 1980; Suresh, 1998), they include observations of microstructures in the incubation period (small cracks, slip bands, dislocations, etc); nondestructive evaluation of micro-structure change using ultrasonics, X-ray, and magnetic methods; and fracture mechanics to predict the remaining life. These efforts produced an essential view of fatigue and its understanding physics.
