Fatigue Analysis in Workbench© 2006 ANSYS, Inc.• Non-constant amplitude, non-proportionalloading– Most general case and is similar to Constant Amplitude,non-proportional loading, but in this loading class thereare more than 2 different stress cases involved thathave no relation to one another– Not only is the spatial location of critical fatigue lifeunknown, but also unknown is what combination ofloads cause the most damage– Thus, more advanced cycle counting is required suchas path independent peak methods or multiaxial criticalplane methods– Currently the ANSYS Fatigue Module does not supportthis type of fatigue loadingANSYS, Inc.

Fatigue Analysis in Workbench• Mean Stress Correction– Cyclic fatigue properties of a material are oftenobtained from completely reversed, constantamplitude tests– Actual components seldom experience thispure type of loading, since some mean stress isusually present– If the loading is other than fully reversed, amean stress exists and may be accounted forby using a Mean Stress Correction© 2006 ANSYS, Inc.ANSYS, Inc.
