The primary application of the Stress-Life method is high-cycle fatigue (long lives), where nominal stress controls the fatigue life. A wide range of methods are available for defining the S-N curves, including the ability to interpolate multiple material data curves for factors such as mean stress or temperature. underground wonder bar who is playing tonight
