Acoustic Emission of Growing Microcracks in Vibration-Loaded Material [PDF]

open access: yesarXiv, 2006
We propose mechanism describing an acoustic emission by growing microcracks in the material under external cycled load. We use the theoretical approach based on Huygens principle for elastic solid con-tinuum with an account for dislocation creep in the zone of abrasive action.
