✦ Synopsis

The results of most diagnostic techniques based on modal analysis strictly depend on the accuracy of the structural analytical model that one uses, on the measurement errors and on the severeness of the damage to be identified. The sensitivity of a particular damage identification technique is discussed and it is shown that the above aspects are crucial even when dealing with simple structural models.
