Fatigue Life Calculator

Fatigue life is defined as the number of load cycles that a stressed metallic component would be able to sustain before it fails. From a reliability point of view, assessment of fatigue life is essential, especially for a component experiencing continuous fluctuating stress. There are three well known fatigue analysis methods: (i) stress life, (ii) strain life and (iii) fracture mechanics. The software here estimates fatigue life using stress lie or S-N method. The inputs to the software are magnitude and nature of stress on component, its UTS, S-N curve slope, and its manufacturing process. The software outputs fatigue life in terms of number of loading cycles.
