Within the presented project two different concepts for a vehicle front structure in multi-material-design (steel, aluminium, magnesium, plastic) have been developed. The progressive, weight-optimised concept led to a weight reduction of approximately 38% (24,9 kg), compared to the conventional structure of the reference vehicle. The weight of a slightly more conservative, cost-optimised concept could be reduced by 18% (11,2 kg), while crash and stiffness performance of these two concepts were at least as good as the reference. For weight comparison, only modified parts were taken into account. Besides the development of the concepts the development of a material model for the simulation of adhesive bonding under crash load was developed. This model is based on test results that were generated by using different test samples under different loads. A cost analysis of both the reference structure and the newly developed concepts concluded the work of this project.
