Abstract Scope |
Evaluating the mechanical properties of parts fabricated using AM is not a one-size-fits-all process. The material response to stress is highly dependent on the specific conditions of the application. In this work, the material properties of stainless-steel test samples fabricated using LPBF when subjected to rapid loading conditions will be assessed.
High velocity gas gun uniaxial strain plate impact experiments were performed to analyze this behavior. Test scope includes examination of build orientation dependence and effects of engineered porosity distributions on wave propagation, damage characteristics, and material response properties in AM materials. Data collection through a combination of in-process velocimetry, microstructure analysis, and post-mortem characterization of soft-recovered samples is used to develop process-structure-property relationships. Focus of this discussion will be on the wave propagation, microstructure, and resulting damage evolution observed in these experiments. |
