d="p0005">The theoretical basis of the modal frequency curve method is established.

d="p0010">Extraction of defect features from frequency curve via wavelet decomposition shown.

d="p0015">New multiple-mode wavelet-based squared residual damage indicator is proposed.

d="p0020">Damage size estimator based on standard deviation of the indicator is presented.

d="p0025">Damage indicator gives a more robust and unambiguous damage identification.
