I am trying to do a fatigue analysis on the uPVC pipe. I was able to find the uPVC material in the Ansys but it does not contain the fatigue properties. I got an error message "an error occurred inside fatigue module, invalid or missing stress life curve" I want stress life curve.

Look for that in the literature/Internet or plan to perform material testing to create your own stress-life data.

You may find some data in this paper: https://link.springer.com/article/10.1023/A:1021899801981
And you can find fatigue strength data in Ansys Granta EduPack or Ansys Granta Selector for different PVCs, but I can't find any S-N curves sorry.
