Using Amplitude Analysis of Acoustic Emission Signals under Cyclic and Static Loading of Steel Samples
The results of amplitude analysis of discrete acoustic emission signals from developing sources such as fatigue cracks are presented. The studies were carried out on three groups of samples with stress raisers. The specimens were made of ordinary grade structural low-carbon steels, quality steels, a...

description | The results of amplitude analysis of discrete acoustic emission signals from developing sources such as fatigue cracks are presented. The studies were carried out on three groups of samples with stress raisers. The specimens were made of ordinary grade structural low-carbon steels, quality steels, and low-alloy cast steels and were loaded with tensile static and combined loads, including static and cyclic loads. A power-law dependence has been established of the distribution density of the amplitude of signals with a high correlation coefficient for sources of acoustic emission, which varies little at different stages of crack growth, with the exception of the stage preceding the fracture. The studies have made it possible to use the amplitude distribution of signals to determine the number of acoustic emission signals from sources such as cracks located at different distances from the receivers and taking into account the attenuation of the wave energy. |
