Acoustic emission: data analysis and applications

摘要

Some applications and state-of-art of acoustic emission techniques are introduced in the present paper through an overview of publications in acoustic emission techniques. Attention is given to applications of acoustic emission techniques to the condition monitoring and damage feature extractions of reinforced concrete structures. With the use of numerical examples, major acoustic emission signal processing methods such as the wavelet transform, the Gabor transform, the bilinear time-frequency distribution, and the cepstral analysis are discussed.
