What is Damage Detection with Spatial Wavelets about?

This paper discusses a structural damage detection technique based on wavelet analysis of spatially distributed structural response measurements[ The premise of the technique is that damage "e[g[ cracks# in a structure will cause structural response perturbations at damage sites[ Such local perturbations\ although they may not be apparent from the measured total response data\ are often discernible from component wavelets[ The viability of this new technique is demonstrated with two examples] one based on numerically simulated de~ection responses of a uniform beam containing a short transverse crack under both static and dynamic loading conditions\ and the other based on smooth analytical crack!tip displacement \_elds[ In each of these examples\ the de~ection or displacement response is analyzed with the wavelet transform\ and the presence of the crack is detected by a sudden change in the spatial variation of the transformed response[ This damage detection technique may serve the purpose of structural health monitoring in situations where spatially distributed measurements of structural response in regions of critical concern can be made with\ for example\ networks of distributed
