Signal Processing for Damage Detection

This article is intended to provide motivation for the study of signal processing methods in the context of Structural health monitoring (SHM). Apart from providing a brief discussion of the main areas of SHM in which signal processing is required in order to make progress, the article provides a roadmap for the signal processing part of the Encyclopedia and guides the reader to the more detailed expositions of the various topics. Keywords: signal processing; model-based SHM; signal-based SHM; feature selection; pattern recognition; machine learning; uncertainty analysis
