Simulation of measurement uncertainties and their effect on practical applications of test data

Many modal analysis applications these days try to incorporate experimental data of test structures into their formulations because experimental data represents the most accurate form of information one can gather about that structure. Ironically, in the effort to measure structural responses with h...
