The S-N curve, also called the Wöhler curve, is one of the most popular methods for fatigue evaluation. The curve relates stress amplitude to the limiting fatigue life and can be obtained directly from a set of standard fatigue test. Many times our applications are subjected to conditions different from the experimental conditions of the fatigue tests. The fatigue data must then be appropriately modified in order to take the actual operating conditions into account.

In the example it is shown how to perform a fatigue evaluation when the material data needs to account for harsh environmental conditions and poor material process. A parametric sweep is used to evaluate fatigue response of two conditions. A tutorial model from the Structural Mechanics Module of a bracket is examined.
