ABSTRACT:
A transducer acoustic emission testing of a structural part includes a commercially available accelerometer having at least one piezoelectric element and one seismic mass. The accelerometer is typically tuned to a resonant frequency substantially between 1 kHz and 100 kHz. The accelerometer is coupled to the structural part in a frequency range substantially from 0.1 MHz to 2 Mhz.
