Abstract

The innovative production methods Composite Extrusion and Friction Stir Welding are used to manufacture lightweight frame structures made of steel reinforced aluminium. In order to optimise the processes themselves and the manufacturing of frame structures both processes are analysed in a structural simulation. One result of these simulations is the distribution of the residual stresses in the reinforced profiles. The simulation results are compared with measurements of the residual stresses by means of neutron scattering.
