Imaging of local stiffness of damaged polycrystalline copper : nondestructive evaluation by resonance ultrasound microscopy
The distribution of the local stiffness of a polycrystalline copper exposed to a creep test was studied by resonance ultrasound microscopy. The local effective modulus was evaluated from the resonance frequency of the isolated langasite oscillator touching the specimen. Defects appeared predominantl...
