Abstract

This chapter reviews and compares some of the most known methods of damage identification, in the frequency domain, which use operational deflection shapes (ODSs) built from the frequency response functions (FRFs). Two new methods of damage identification, in the time domain, using (ODSs) built from the time responses are also analyzed. To assess the performance of the different indicators, two numerical tests are undertaken with a finite element model (FEM) model, of a cantilever beam, to evaluate their detection and localizing ability.
