Correlation between acoustic emission parameters of a growing crack, the stress intensity factor, and the type of stressed state
Source abstract
Abstract
Correlation between acoustic-emission (AE) parameters of a growing crack and the stress intensity factor in its vicinity was studied experimentally for various types of stress states. Physical interpretation was made for the maxima of the detected amplitude and for specific stages in the length dependence of the total number of AE acts produced by the crack. It is recommended to use the results obtained for improving reliability of the AE testing technique of the prefracturing state.
