Automotive applications involving forming stages during the manufacturing process and/or in service crash resistance require aluminium alloys with optimized mechanical characteristics and careful choice of section geometry. This study presents a numerical simulation approach for design of aluminium alloy extrusions for such applications. The numerical calculations are based on both implicit and explicit finite element codes. Experimental bending and energy absorption tests were been conducted using different 6xxx series alloys heat treated to different strengths. Further validations of the simulations have been conducted in collaboration with automotive suppliers. The numerical tools enable rapid evaluation of effects of section shape, alloy composition and heat treatments, assisting design optimization with extruded semi-products in order to achieve very significant weight reductions in automotive structures.
