nonlinear buckling

hi all,

      im doing m.tech structures,i ve doubt abt nonlinear buckling of perforated plate subjected to uniform compresssion load.i diddn't get exact buckling load load in nonlinear analysis,my problem is how to load vs displacement curve.plz help me.

            thank u

First enter timehisyory postprocessor after your nonlinear analysis.then use define variable icon to choose one of model’s node and dof .then enter variable viewer finally plot your load displacement curve.

thanks a lot

 i ve another doubt about nonlinear buckling im getting some results,im not getting exact inelastic buckling load.i appled geometric imperfection to plate.then also im not getting.how to get exact value,from graph plz explain clearly.i already told my model is perforated plate subjected to uniform pressure.

thanks in advance
