Abstract
A resonant-ultrasound-microscopy method has been developed for measuring the local Young's modulus of a material. This method detects the effective Young's modulus through the resonance frequency of a langasite (La3Ga5SiO14) oscillator touching the specimen. Because the vibration of the oscillator is induced and detected with a solenoid coil in noncontacting, wireless, and electrodeless way, it is affected only by its contact with the specimen, achieving an absolute measurement. Elastic-constant mapping was performed on cross sections of a duplex stainless steel and a NbTi/Cu superconducting wire. Analysis with the static contact stiffness predicts the frequency change smaller than that measured, and the necessity of considering the dynamic contact stiffness is discussed.
