Parameter based AE analysis
Boekbijdrage - Hoofdstuk
The present chapter discusses the parameter-based analysis of AE. This is particularly useful in case full
waveform recording is not available, or the acquisition rate is not sufficient to allow waveform streaming.
Parameter analysis is based on extraction of descriptors that contain most of the waveform information,
without however, the need to store the whole number of points, essentially contributing to data
management. The different parameters are introduced and their relation to fracture mode as well as their
use for process characterization are discussed in detail. In addition, well established indices based on the
total AE activity are also discussed to demonstrate the complete arsenal of AE parametric analysis that has
proven very useful to researchers and practitioners, in different material systems.
