Abstract
An acoustic‐emission loading and detection system is described and the detection system's harmonic response to both longitudinal and flexural waves is evaluated. Photographs of acoustic‐emission response pulses are presented, and it is shown that the flexural waves are of considerable importance in describing the detection systems's response to the acoustic‐emission source pulse. An estimate indicates that the energy of the flexural part of one acoustic‐emission pulse is two orders of magnitude greater than the energy of the longitudinal part.Keywords
