Fatigue Model

Analyze the Relationship between Stress and Number of Cycles

The Fatigue Model platform enables you to analyze fatigue data, which is also known as S-N (strain or stress versus number of cycles) curve modeling. The platform provides a variety of model types. All of the model types can be fit using one of four conditional distributions. The models either fit the fatigue-strength distribution conditional on the number of fatigue cycles or fit the fatigue-life distribution conditional on the fatigue-stress setting.

For more information about fatigue models, see Meeker et al. (2022).
