Question

Find the correct statement(s). 0 In high-cycle fatigue domain the stresses are relatively high and fatigue lives are relatively long. In low-cycle fatigue domain the stresses are relatively low and fatigue lives are relatively long. Fatigue crack growth rate is almost a constant from the crack initiation to the final failure. OD Cracks associated with fatigue almost always appear deep inside the material (opposite to the brittle fracture). E. Statements A)-D) are incorrect.

Answer 1

Step-by-step explanation:

E. Statements A)-D) are incorrect.

Step-by-step explanation:

In the high-cycle fatigue domain, the stresses are relatively low and fatigue lives are relatively long. In contrast, in the low-cycle fatigue domain, the stresses are relatively high and fatigue lives are relatively short. Fatigue crack growth rate increases as the crack grows, leading to accelerated failure. Cracks associated with fatigue can appear on the surface or near the material's surface.
