The theoretical basis of the modal frequency curve method is established.
•
Extraction of defect features from frequency curve via wavelet decomposition shown.
•
New multiple-mode wavelet-based squared residual damage indicator is proposed.
•
Damage size estimator based on standard deviation of the indicator is presented.
•
Damage indicator gives a more robust and unambiguous damage identification.
