title: Time-frequency and time-scale analyses for structural health monitoring.
abstract: Signal processing is one of the most important elements of structural health monitoring. This paper documents applications of time-variant analysis for damage detection. Two main approaches, the time-frequency and the time-scale analyses are discussed. The discussion is illustrated by application examples relevant to damage detection.
