Abstract

The growing market for additive manufacturing processes such as laser beam melting (LBM) poses new challenges. With more difficult product requirements, the need for a deeper understanding of the resulting stress states and the underlying physical principles increases. To gain a deeper understanding of the residual stress states of LBM-manufactured parts, simulations of the build-up process were carried out and validated by means of neutron diffraction (ND), X-ray diffraction (XRD) as well as incremental hole-drilling (IHD). The gathered data is also intended to serve as a validation case for other simulation models and tools.
