Hello,
I am working on Bracket for which i have conducted FRF analysis. Now i what to carry out Fatigue analysis for that one at particular frequency before resonance. How can i carry this analysis now.
Thanks in advance for Reply
You can refer the webinar available on below link for the FRF and Fatigue Analysis of same model.

hello,
Please share Tutorial or case study related to FRF and Fatigue Analysis of same model.
How to give extrication acceleration used in FRF in fatigue Analysis.
Currently in Frequency domain we can do Sine Sweep Fatigue Analysis and Random Response Fatigue Analysis. Please refer attached files.

Sir, Thanks for Reply,
I have ran the .fem i am facing this error
*** ERROR # 1490 *** in the input data: Unexpected continuation card.
This is the new feature in OptiStruct 2017.2.2 .This will run for 2017.2.2 and above version.Latest version is OptiStruct 2018 and latest patch is 2018.0.1
Please share .out file ,if you have used the same version for the run.
No, sir i am working on Hyperworks 14.0
I have small doubt that in new version will it show the life of component. Because i could see only damage in that PDF
For Fatigue Analysis solver gives life and Damage output by default.
Damage = n/N = no. of cycles applied/ Total life
Please refer to our free eBook on Fatigue analysis with OptiStruct using below ink.

There is no example of Random Response Fatigue Analysis in the attached files, I made an example, but it does not work well in Fatigue subcase. The result of Fatigue subcase is blank. Would you check the model for me?
BG!
PFA attached deck for random fatigue.
