Structural Health Assessment Using a Partition Model

چکیده
In this work, a previously proposed minimum rankperturbation theory(MRPT)isextendedtodetermine the damage extenf of each structural element or portion independently. This improved procedure presents the advantage of needing only a small number of modes to assess the damage extent. Two numerical simulated examples and an experimental problem are presented to iliusfrafe fhe characterisrics and improvements associared with the proposed procedure. It is shown fhat fhe present procedure results in a dramatic decrease over the original MRPT in the number of modes needed in assessing the damage.
