Application of Normal Waves for Large Thin-Walled Object Testing: New Methods. Part 3. Technique of Defect Detection in Extended Objects under the Conditions of One-Sided Access

D. A. Terentyev, Yu. P. Borodin

The developed technique for automatic dispersion curves extraction from spectrogram allows for calculating the distance to the signal source with an accuracy to 1 % even when the signal arrives only to one sensor that gives the chance to perform the AE testing in case of one-sided access to a particular extended object.
