Wavelet analysis of static deflections for multiple damage identification in beams

Wavelet analysis can be used in local damage detection due to its ability of revealing discontinuities induced by the displacement field. This paper focuses on application wavelet detect and identify multiple damages using static deflection beams. The are located maxima lines their severity evaluated from a index obtained coefficients along corresponding lines. A series experimental tests were conducted examine performance methodology for scenarios. deflections beam measured Digital Image Correlation system. As an application, l1 regularization based filter is adopted diminish measurement noise which critical analysis. shows capability closely spaced notch-type detection. It also analyzes limits method estimating with relative small presence severe ones.
