| Description |
Acousto-ultrasonic (AU) investigation is a single-sided nondestructive evaluation technique employing two different transducers for sending receiving the acoustic signals. This method is used for assessing the microstructural condition, distributed damage state of the material between the transducers. AU is complementary to more traditional NDE methods such as ultrasonic c-scan, x-ray radiography, and themographic inspection that tend to be used primarily for discrete flaw detection. Through its history, AU has been used to inspect polymer matrix composite, metal matrix composite, ceramic matrix composite, and even monolithic metallic materials. Our group is working on the development of AU scan system with insitu piezoceramic coating for charactering material inhomogeneity and structural health monitoring of the systems. This research will greatly aid the aerospace industry for health monitoring of both metallic and composite structures. In this report, a current scenario in the field of AU technology is reviewed.
