14.2.2. Fatigue Evaluation

This function is most important key function to calculate the fatigue results. So, this function contains a lot of criteria that are the equation to calculate the fatigue results from a SN Curve of the selected fatigue material. In addition, it supports the material library with 180 common fatigue materials based on SAE J1099. Besides several life criteria and fatigue materials, this function supports selecting time history for the Rainflow Counting from given stress or strain results of flex body, choosing the element set or patch set defined at the Body Edit mode, defining the occurrence of time history, and showing the maximum fatigue damage and the minimum fatigue life.
