An exact formulation for structural dynamic model error localization
Gordis, Joshua H.

The general theory for frequency domain structural synthesis is based on a structural synthesis transformation, a direct analytic relation between two frequency response function structural models. This transformation provides an exact formula for the localization of finite element modeling errors, independent of error magnitude. The localization matrix plays a critical role in the associated theory of frequency domain structural identification, as it provides the information required to insure a unique solution for the modeling errors. The localization matrix is seen to be general frequency domain statement of the error matrix and unity check methods. Methods for the practical implementation of frequency domain localization are presented. The implication of such methods are discussed.
