Abstract Scope |
Additive manufacturing offers a means to design very complex thin-walled components that could have spatially varying material properties due to local processing variation. For design purposes, there is a need to be able to link local, geometry-dependent processing conditions to properties/performance of the overall component. As a building block towards this realization, the MIDAS program generated highly-pedigreed tensile properties at room and elevated temperature for thin-walled milli-scale specimens made from an AM Ni-alloy. The aim of this work was to help build a material property database for geometry-based design approaches, such as topological optimization. A design of experiments was conducted that included parameters such as build orientation, wall thickness, and surface condition (as-built versus surface ground) for a couple different processing conditions. Results from thin-walled milli-scale mechanical testing and future implications of this work are discussed. |
