Now i understand what legend you are reffereing to. Unfortunately i am not using the Workbench for my analysis. After some more research i found that when using the ls-dyna solver directly the eigenvalue of the eigout file always represents the load factor and it does not matter if the base simulation is linear or nonlinear. Therefor i assume that the good results are due to the small deformations at the buckling load and the low stresses in the material that are within the elastic range. In the Guidlines for implicit analysis it says that imperfections are also neglected. Can you explain what those imperfections are ? if the imperfection would be a dent then this would be included in the stiffnessmatrix as i understand this.Â
