Acoustic study of dislocation rearrangement at later stages of fatigue: Noncontact prediction of remaining life

This study is devoted to clarifying the mechanism of the surface-shear-wave attenuation peak observed during rotating bending fatigue of carbon steels. We have developed electromagnetic acoustic resonance to make a contactless monitoring of the attenuation throughout the fatigue test. The attenuatio...
