Hello Peter,

Thank you for your detailed answer. There could be no better answer to my question than this. It's amazing to be able to get support from you.

I have one more small question. You know, after an FEA simulation is done, the stress values are compared to material properties. For example, we compare the equivalent stress results with yield stress in static analyses and fatigue strength in vibration analyses. When beam modeling is performed in vibration analyses, we obtain normal stress and shear stress values.

Which stress values should I compare with the fatigue strength of the material in vibration analyses? I would like to ask the same question for static analyses.
