Abstract

Resonant measurement, or using sound to provide insight into a material’s condition, has been used for 100s of years. Very simply, this would take the form of listening to the “ring” of an object when struck sharply. Such approaches have been historically employed in casting, for example in the manufacture of clock tower bells, or for rudimentary non-destructive testing (NDT), for example wheel tapping in the rail industry. Acoustic methods have since progressed to become more quantitative than qualitative and there are now several different instrumented methods and analyses available. This measurement note introduces resonant methods and describes the application of Resonant Ultrasound Spectroscopy (RUS) to the quantification of anisotropy in additively manufactured materials.
