| Abstract Scope |
Additive manufacturing (AM) has enabled the creation of components with complex geometries, unique processing advantages, and simplified designs. Despite the major advantages that this technology affords, difficulties in validating additive components for critical applications in aerospace has limited its widespread usage. Variables such as beam settings, part geometry, and material specific parameters can cause massive variations between additive parts and builds. Resonant Ultrasound Spectroscopy (RUS) is being investigated as a non-destructive evaluation (NDE) technique that can characterize and validate additively manufactured nickel alloy components. The ability of RUS to detect build defects and variations in print structure will be discussed for a nickel-base alloy printed by laser powder bed. Finite element simulations have been conducted to compare resonant behavior to experimentally measured broadband resonant spectra and to assess the sensitivity of the technique to additive process variations. |
