Perturbation damage indicators based on complex modes [PDF]

, 2017
The papers focusing on dynamic identification of structural damages usually rely on the comparison of two or more responses of the structure; the measure of damage is related to the differences of the vibration signals.

Model-Free Method for Damage Localization of Grid Structure

Applied Sciences, 2019
A model-free damage identification method for grid structures based on displacement difference is proposed. The inherent relationship between the displacement difference and the position of structural damage was deduced in detail by the Sherman− ...

Damage detection in beams from modal and wavelet analysis using a stationary roving mass and noise estimation [PDF]

, 2018
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.
