We are trying to correlate experimental setup which is excited for 4.5 g at 33 Hz for 24 hours
and Stimulate it to FEA, Please can i have a sample deck.or to set the deck for this in FRF analysis
Please refer the attached deck for sine sweep fatigue analysis. Please use OptiStruct 2017.2.2 or above version for analysis. Refer the user guide for the details of sine sweep fatigue analysis.

Thanks Rahul,Please let me know that Frequency Response will have Various Frequency and at which frequency we are Getting maximum,
But
My case the excitation frequency and amplitude is constant over a particular time period
that is excitation frequency is 33 HZ and 4.5 G level.
Please try with modal transient analysis.
How to do fatigue for this
PFA sample example for Modal Transient Fatigue analysis.
Thanks i will let you know for further doubts
