Abstract
We analyze the results of application of wavelet transforms to the analysis of acoustic-emission signals accompanying fracture processes in structural materials and the data of engineering diagnostics of various industrial objects. The methods used for the identification of the types of fracture processes in materials (steels, alloys, polymers, etc.) with the help of wavelet transforms are characterized. We consider the possibilities of wavelet transformations of acoustic-emission signals for the determination of the mechanisms of fracture in composites and processing of the signals of magnetoacoustic emission. Examples of the tests performed in the Physicomechanical Institute of the Ukrainian National Academy of Sciences and demonstrating the efficiency of wavelet analysis of signals are also presented.
