Damage detection in beams from modal and wavelet analysis using a stationary roving mass and noise estimation
(Wiley, 2018-04)
This paper uses the Continuous Wavelet Transform Analysis on mode shapes for damage identification. The wavelet analysis is applied to the difference in the mode shapes between a healthy and a damaged state. The paper also ...
