Abstract
A cross-spectral correlation function of a structure may be determined by providing a finite element model of the structure having a plurality of elements each having a centroid. A plurality of composite centroids may be determined wherein each one of the composite centroids is based on at least one of the elements. The cross-spectral correlation function between at least one pair of the elements in the finite element model may be assigned to be the cross-spectral correlation function of the composite centroids that include the centroids of the elements. If the pair of elements is included in the same composite centroid, then the cross-spectral correlation function between the elements is assigned to be the autocorrelation function of the composite centroid that includes the pair of elements.
