摘要

A system includes at least one circumferentially-polarized d₁₅shear ring transducer and a controller electrically coupled to the at least one circumferentially-polarized d₁₅shear ring transducer. The at least one circumferentially-polarized d₁₅shear ring transducer is configured to be disposed on a structure and to detect at least one shear horizontal-type acoustic emission from damage to the structure. The controller includes a machine-readable storage medium and a processor in signal communication with the machine-readable storage medium. The processor is configured to store acoustic emission signal data in the machine-readable storage medium when a signal amplitude detected by the at least one circumferentially-polarized d15 shear ring transducer crosses a first threshold.
