Autotuning of Isotropic Hardening Constitutive Models on Real Steel Buckling Data with Finite Element Based Multistart Global Optimisation on Parallel Computers

Figure 10

FE load-displacement traces obtained with the best buckling and tensile estimates of the global optimum, MPa, MPa, , and (see Table 3), are shown as symbols. Superimposed lines show the experimental data. Note that the curves are deliberately separated for clarity, via arbitrary scaling of the load for each dataset. The plot is used exclusively to highlight a match between the FE and the experiment for each geometry.
