Fatigue analysis is an important aspect of component design. Typical yield stress design criteria miss the fatigue cycles seen in actual service use and hence can lead to improper design. Fatigue Analysis helps to identify how repetitive load cycles cause structural failures. Fatigue analysis and fracture mechanics are essential to understanding the life of the structural for crack initiation and crack propagation to in order to extend serviceability.
