Abstract

Due to environmental concerns and safety regulations in the automotive industry the development of strong and lightweight cars has been a very significant topic in the last years. One of possible solutions to this matter is to use materials with lower density or lower thickness. However, the demand to increase passive safety requires using of materials of higher strength. The goal of this research is to evaluate feasibility of selected outer body parts using HSS steel, DP500 (dual-phase). DP500 provides higher yield and ultimate strength than conventionally used mild steel at the expense of lower ductility, plastic anisotropy ratio and strain hardening exponent. Impact of different geometrical shape and influencing process conditions and parameters are discussed in this article. The evaluation of feasibility is performed in software AutoForm R6. This research is carried out in cooperation with ŠKODA AUTO, a.s.
