In recent years, Resonant Ultrasound Spectroscopy (RUS) has been extensively applied to objects produced by additive manufacturing characterize elastic material properties, detect defects or geometrical deviations. this talk, we analyze samples that were using the wire-arc (WAAM) process different grades of steel wires. Resonance spectra obtained and allowed classify as either elastically isotropic anisotropic. Detailed investigation on anisotropic (produced with 316L wire) under an orthotropy hypothesis showed markedly softer along layer deposition direction. Subsequent EBSD confirmed results RUS. They also quantitatively model constants Voigt-Reuss-Hill averaging theory, which in good agreement ones RUS inverse problem.
