Figure 1.5. Process of fatigue crack initiation in nonferrous metallic materials. (a) Crack initiation and propagation in 70/30 brass. A crack initiated at the stress σ 1 needs N=10 8 or 10 9 additional stress cycles to cause failure. However, at the slightly increased stress level, σ 2, crack growth starts immediately, and leads to specimen failure without coaxing effects.
