Abstract

The ability to predict and to measure the ODS of a vibrating structure suggests its use to increase the potential for structural damage detection, localization and severity assessment with high spatial density. Previous research based on simulation and testing of some simple test cases showed the effect of excitation locations on structural damage detection. The measurement of the ODS, at specific excitation location, of healthy and unhealthy structures showed a substantial difference in the deflection shape of the structures. Following the positive results of the simulations and measurements of ODS between undamaged and damaged strucuture, it can be possible to start a theoretical identification of the damage location. Results of the damage location identification will presented and discussed.
