Damage Detection Using Prior Wavelet Decompositions


Article Preview

This work was conducted as part of the European Union project ARTIMA and it investigates the effectiveness of wavelets in damage detection. It examines whether a prior wavelet decomposition of Lamb wave responses facilitates the classification of structural damage. The structure in question is an aluminium plate with viscoelastic-mounted transducers, and the damage took the form of saw cuts on the plate. The novelty detection technique of outlier analysis was used to classify the damage.
