Hi
I have 2 timevarying non-constant amplitude loads on a part as seen in attached image. I want to find out fatigue life in ansys workbench. In static analysis I apply these 2 load cycles to the part. When fatigue tool is inserted in the environment, I think I will need to import the "historydata" file becuase these are iregularly varuing loads. Here I have a doubt which I have defined in the attached image. Please let me know what value should be there in the "history" data file
Should I import same loads again one after other in a file as in static analysis OR
Should I add the 2 load series and import the file OR
Should I add the 2 load cycles and divide by the sum of their peaks to get a "normalized" history data?
Your suggestion will be greatly helpful.
-Regards and Thanks
