 I made a PSD fatigue model based on my understanding to Optistruct, but I do not know whether this is the right setting, I see the stress PSD and RMS stress is similar with Patran, but I am not sure about the fatigue damage results, is there someone who can help me to check?

Thanks a lot!

 

Notes:

In my model, a simple beam is built, on the tip of this beam, a 0.2kg mass is added. Then the other end of this beam is fixed, and the PSD loads in here is 0.475G^2/Hz from 20Hz to 200Hz, this random test keeps for 4 hours.
