Electromagnetically excited ultrasonic waves applied to experimental mechanics
Abstract
The noncontacting nature of electromagnetic acoustic transducers as well as their discrimination features are reviewed along with applications employing these properties. Focus is placed on high-temperature measurements, measurements inside a vacuum chamber, flaw detection under clamping jaws, surface-crack depth measurements, precipitate morphology measurements, and noncontact strain gages.
