N2 - Composite profiles composed of aluminum base material and steel reinforcing elements manufactured by bar extrusion exhibit residual stresses. These stresses occur due to the different thermal shrinkage of the materials during cooling of the profile. In this paper, the residual stresses are investigated by means of analytical and numerical analyses. The influence of the reinforcing volume and the material behavior, i.e. the plastification of the base material, is discussed. Furthermore, the residual stresses in symmetric profile cross sections with multiple reinforcings are examined and compared to the stresses in a simple composite rod with a centric reinforcing.
