| Abstract Scope |
AlSi10Mg, fabricated by the laser powder bed fusion (L-PBF) additive manufacturing process, offers many advantages compared to traditional cast material. In this study, its tensile properties are evaluated by investigating global and local deformation behavior via extensometer and strain gauge sensors, respectively. Specimens are built using recycled AlSi10Mg powder on ProX-320 L-PBF equipment using vetted process parameters, as suggested by 3D Systems. The as-built specimens contain a one-sided V-notch to precisely control the onset of failure. Strain gauges are installed near the notch region and the specimens are tested on an MTS 50 kN electromechanical load frame. The results show the strain gauge records higher strain in comparison to the extensometer due to its proximity to the notch tip. The experimental findings are also corroborated with finite element-based simulation results. In summary, this work establishes that strain gauge sensors can be used for online health monitoring of additive manufactured specimens. |
