Extracting Stress/Strain results from frequency response analysis

Extracting Stress/Strain results from frequency response analysis

Extracting Stress/Strain results from frequency response analysis

(OP)
Hello!

I am currently performing frequency response/transient response analysis (direct and/or modal) using Radioss 10. From what I know, the results are available as frequency response function, ie, the displacement magnitude and phase graphs. While this is helpful in understanding the system resonances, I am inerested in finding out the stresses and strains induced in the component at this resonant frequency. Further, there is a requirement to optimise the stress levels in the component (not necessarily at that frequency as any structural modifications will change the FRF). I know ANSYS has a procedure called 'Expanding the Modes' which essentially is a second run of analysis for extracting stresses and strains at the specified frequency and phase.
So, does Radioss provide such an analysis sequence, and if so, could someone be kind enough to explain the procedure?
