Abstract

The resistance of metal alloys to fatigue can be classified into four major regimes: low-cycle fatigue (or short life), limited resistance (between 105 and 106 cycles), high-cycle fatigue (between 106 and 107 cycles) and gigacycle (more than 107 cycles). This chapter introduces the basic concepts of cyclic mechanical behavior, crack initiation and propagation in these different regimes.
