I am using PLA material for my analysis. I plotted the SN curve but when I am solving the analysis, I get the above error for fatigue tool, invalid/missing stress life curve.

How do I resolve the issue.

Hi,

Please see if the following link helps:

https://innovationspace.ansys.com/forum/forums/topic/module-invalid-or-missing-stress-life-curve/

Also does it work with normal Structural Steel (Ansys material) that has SN curves defined?

If yes, then your S-N data (and other properties) might be wrong or missing.

All the best

Yes it does work now.

Thank you,
