Abstract
A frequency domain theory for structural dynamic model error localization is applied to thedamage detection problem. The localization theory is based on a transformation of the frequencyresponse function matrix, and represents an exact solution for the location of the differencesbetween two frequency response function models, given spatially complete data. The localizationis performed at all frequencies in a chosen bandwidth, and therefore implicitly accounts for allmodes of interest. Methods for coping with spatially incomplete data are explored analyticallyand in an experimental study of a composite beam with installed damage of known length.
