Statistical damage identification method based on dynamic response sensitivity

Journal of Low Frequency Noise, Vibration and Active Control, 2020
The traditional deterministic damage detection method is based on the assumption that the measured data and the finite element model are accurate. However, in real situation, there are many uncertainties in the damage identification procedure such as the
