Setup for Acoustic Emission Testing

Acoustic emission testing (AE) and test procedures comprise three main elements, shown in Figure 1. First, the structure under test is instrumented with AE equipment, sensors, and electronics (the setup). Then, it is loaded (stressed) to stimulate defects, causing them to release acoustic emission waves. The acoustic emissions are sensed, detected, and measured by the equipment, and a suitable record is made. Finally, the record is analyzed to evaluate the condition of the structure.
