Abstract

This article reviews the application of acoustic emission (AE) for structural health monitoring. The basic principles of AE are explained and a historical background is given. The different types of AE, the wave propagation, the detection, the Kaiser effect and the Felicity ratio, the signal analysis, and the localization and discrimination methods are described in detail. This is followed by a literature review on the most common applications of AE for structural health monitoring. The article concludes with some future prospects of AE.
