Damage localization in structures without baseline modal parameters
Abstract
A methodology to localize and estimate the severity of damage in structures for which only postdamage modal parameters are available for a few vibrational modes is presented. First, a theory of damage localization and severity estimation that utilizes only changes in mode shapes of the structures is outlined. Next, a system identification method that combines the experimental modal data and the modal parameters of a finite element model of the structure under investigation is developed to yield estimates of the baseline (i.e., predamage) modal parameters for the structure. Finally, the feasibility and practicality of the complete damage detection algorithm are demonstrated by localizing and sizing damage in a continuous beam for which only postdamage modal parameters for a single vibrational mode is available.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
