A Review on Effective Acoustic Emission

To improve nondestructive evaluation (NDE), the dependences of acoustic emission testing were investigated. Acoustic emission testing, is a technique in the NDE field that has multiple different advantages. Its versatility allows engineers and other researchers to detect and monitor flaws and discontinuities within different materials. This report will describe how acoustic emission (AE) testing is being used to monitor materials such as metal, concrete, composites, polymers, and wood. This will be done by explaining a brief theory and provide examples of AE and how it’s applied to different materials. NDE is an important field within engineering because it evaluates complex components of a system and provides data related to the health of these components without damaging them. This paper describes in detail the AE detection and verification process in order to give some references for the industry counterparts, while promoting the development of the AE technology.
