Amplitude Distribution Analysis of Acoustic Emission Signals.
Abstract
Acoustic emission signal characterization via amplitude distribution analysis is discussed from theoretical and experimental viewpoints. Fundamental amplitude distribution characteristics of continuous- and burst-type acoustic emission signals are derived and compared with experiment. Regardless of the signal bandwidth, continuous-type signals exhibit the Rayleigh-type peak distribution. Relationship between the amplitude distribution of acoustic emission counts and the peak distribution of burst signals is discussed, considering three model peak distribution functions. Proposed in this paper are new calibration method of acoustic emission instrumentation and a means to separate the contributions of continuous- and burst-type acoustic emission signals.
