摘要
A method for identifying the stages of deformation and destruction processes in materials on the basis of detection and location of the critical points (local extrema and inflection points) of the recorded parameters of the reconstructed flow of acoustic-emission events. The issues of the applicability of this method to both the flaw-formation processes and the phenomenon of Poisson flow of events accompanying the AE model. A method for reconstructing the parameters of the initial flow of AE events inside a material based on the recorded AE signals is described. It is shown that the reconstruction procedure appreciably increases the accuracy and reliability of the results of AE diagnostics of the stages observed in flaw-formation processes.
