1. Material fatigue

Depending on the nature of the operating conditions, fatigue cracks can be classified into two mechanisms: Thermo-Mechanical Fatigue and High Cycle Fatigue. Wöhler curves or S-N curves (Stress – Number of cycles) are used to design parts for fatigue loading. These curves are defined for each type of material.

For example, a cylindrical specimen of a given material is rotated around its axis of revolution...
