<strong>Fatigue</strong> Analysis in <strong>Workbench</strong>• Non-constant amplitude, proportional loading– The <strong>ANSYS</strong> <strong>Fatigue</strong> Module uses a “quickcounting” technique to substantially reduceruntime and memory– In quick counting, alternating and mean stressesare sorted into bins before partial damage iscalculated– Without quick counting, data is notsorted into bins until after partialdamages are found– The accuracy of quick counting isusually very good if a proper numberof bins are used when counting© 2006 <strong>ANSYS</strong>, Inc.<strong>ANSYS</strong>, Inc.
