    question on modeling stress stiffening effect

      Hi,

       

      I am trying to model the resonant frequencies of a clamped beam subjected to various axial load. I found the frequency study didn't include non-linear analysis. I wonder if anyone here would have any good suggestion.

       

      Thanks,
