Abstract:
The design space of topology optimizations is often limited by installation space limitations and interfaces to other components, which can result in local stress concentrations in the resulting notches. In this paper, the potential of microstructure grading was investigated by means of FE analyses on the basis of two components. In experimental investigations of L-PBF manufactured tensile specimens made of AlSi10Mg, a producible variation range of the Young’s modulus from 46 to 62 GPa could be determined. By grading the Young’s modulus, a local stress reduction of 18.6% and 25% could be achieved by means of FE analysis, as well as a slight displacement of the stresses around the critical area.
