| Abstract Scope |
The residual stress state of an additively manufactured component can significant impact on service life. Accurate and highly controlled measurements of these stresses play a crucial role in validating predictive AM manufacturing models. To directly and non-destructively map the residual elastic strains in AM-bench bridge structure geometry samples, Energy dispersive X-ray diffraction experiments (EDD) were conducted at the Structural Materials Beamline (SMB) at the Cornell High Energy Synchrotron Source (CHESS). In these experiments, a polychromatic X-ray beam with an energy range between 50 keV to 150 keV was utilized to evaluate high resolution (spatial) residual strain maps of AM – Bench samples. In this presentation, we will review the EDD technique and the AM – Bench experiment in detail. The data analysis strategies, including different analysis algorithms and their implications, will be discussed. |
