3 Terms and definitions

GB/T 12604.4 defined and the following terms and definitions apply to this document. 3.1 Acoustic emission source acousticemissionsource The physical source or location of a material that generates a transient elastic wave with rapid energy release. 3.2 Acoustic emission source acousticemissionlocationsource The position of the acoustic emission source on the test object is determined by analyzing the acoustic emission data. Note. Several common source positioning methods include zone positioning, calculation positioning, and continuous signal positioning. 3.3 Active activity The number of AE events varies with the loading process or time. 3.4 Intensity The average elastic energy released by acoustic emission source events. ......
