As is well known, acoustic emission monitoring is a nondestructive means of evaluation which passively "listens" to sound waves generated by stresses within a material. The out-of-plane displacements created by the sound waves (typically on the order of picometers or smaller) are detected and converted to a voltage by piezoelectric transducers; computerized equipment is used to measure and record the resulting voltage vs. time information. |
