Abstract

Based on the gained knowledge of projects B4 and C5, the aim of this project is to account for the influence of part borders on the resulting material/part-mesostructure for powder- and beam-based additive manufacturing technologies of metals and to model the resulting meso- and macroscopic mechanical properties. The mechanical behavior of these mesostructures and the influence of the inevitable process-based geometrical uncertainties is modelled, verified, quantified and validated especially for cellular grid-based structures.
