stress (repeated or fluctuating). Eliminating any one of the above three requirements will stop the fatigue process. 2. Describe the three stages of fatigue in metals. The three stages of fatigue in metals are: Stage 1: Crack Initiation – Movements of dislocations resulting into slip line and slip planes. It will begin at the point where the local tensile is a maximum. Stage 2: Crack Propagation (Fatigue Zone) – Cyclic tension stresses spread the crack. If the part breaks in one application of
