Fatigue Life Calculation S-N Curve

This App calculates the life (expressed as number of Cycles with probability B50) and the Damage caused by a stress Cycle.

Input data:
1. Material Ultimate Stress [MPa or ksi]
2. Maximum Cycle Stress [MPa or ksi]
3. Minimum Cycle Stress [MPa or ksi]
4. Life Target for the component [B50] - Optional -

As default value, the S-N Diagram assume 0.9 of the Ultimate Stress for the limit of 1,000 cycles [B50] and 0.45 of the Ultimate Stress for the limit of 1,000,000 cycles [B50], but these values can be freely modified.
