Hi, i must to analyze a structure subjects to SIN ON RANDOM VIBRATION.
The output request is the RMS STRESS FIELD for RANDOM FATIGUE VERIFICATION.
The input are 2 PSD curves (one for stocastic sin signal and one for randomic signal).
How i can perform this analysis in OPTISTRUCT?
Is it correct to do two random vibration analysis to obtain RMS stress and after to do a LINEAR SUPERPOSITION?
thank to all
