Tensile behaviour of spring steel wire reinforced EN AW-6082

By Matthias Merzkirch, Marius Meissner, Volker Schulze and Kay Andre ́ Weidenmann


The reinforcement of composite aluminium extrusions offers a high potential regarding weight reduction and improve-ment of mechanical properties, which is essential for components in lightweight constructions. The current work gives an overview of the quasi-static properties of spring steel wire reinforced EN AW-6082 with varying reinforcing ratio. The deformation and damage behaviour is investigated in detail for a reinforcing ratio of 11.1 vol.%. It is shown that the relatively ductile behaviour of the spring steel wire leads to multiple necking resulting in higher strains than expected. Current models are expanded and modified for a proper adaptation to the material system
