It is necessary to select appropriate constitutive material models, and evaluate required parameters for materials used in full-vehicle FE simulations. The parameters for these constitutive material models are usually evaluated by monitoring uniaxial force-extension data from small-scale parallel gauge section specimens. During the material model/parameter verification process, discrepancies between experimental and FE data have been observed. The predictive performance of material models has been held responsible for this discrepancy, however a number of other issues are known to accentuate this disagreement, and the focus of this thesis lies here.
