The study presents the results of research on the problem of obtaining credible results of nonlinear FEM analyses of thin-walled load-bearing structures subjected to post-critical loads. The similarity of numerical simulations results and actual stress distributions state depends on the correct numerical reproduction of bifurcations that occur during advanced deformations process.
