Fatigue

) study is a dedicated study for fatigue evaluation. It processes a load cycle and evaluates a fatigue criterion specified in the Fatigue interface. Before a Fatigue study can be calculated, a load cycle must be simulated. This is done in a Stationary or a Time Dependent study step by simulating structural response to several loading events.

For more information see the Fatigue Module User’s Guide.


	The following applies if you have the Multibody Dynamics Module and want to evaluate fatigue. If the load cycle is simulated using the Multibody Dynamics interface, use the Stationary study instead of the Fatigue study to perform fatigue analysis. The use of a Stationary study in this case is necessary because of how the geometric nonlinearity is evaluated.
