In the nonlinear stiffened plate buckling analysis, I am trying to draw a normalized load shortening curve. According to my knowledge, I need (Avarage stress/σy ) vs (Avarage strain/ ε y).
So I need to have a unitless graph. In the workbecnh I used some probes. I used "reaction force probe" to find the force and I used "deformation probe" to find end shortening.
I want to draw this graph to find the collapse buckling point and initial buckling load.
Can you explain it exactly how to reach the normalized graph like shown in the photo ?
