Abstract

The use of PZT (Piezoelectric Ceramic Lead Zirconate titanate) transducers is increasing in the structural health monitoring in identifying the damage parameters like corrosion, cracks, etc. A Mass and stiffness change due to corrosion in the steel bar is going to influence the structural responses to change. This results in a change of conductance signatures which serve as an indicator of the state of health of the structure. Based on the changes in the conductance signatures of the healthy and damaged bar, the damage extent and location can be identified. In the present study, the conductance signatures of a smart cantilever bar actuated by the PZT patch by voltage excitation are studied. The effect of vibrations on the admittance signatures of the healthy and the corroded smart bar are studied for various patch locations. From the peak shifts of current output obtained for pristine and the corroded bar, it is found that change in EMI signatures serves as a sensitive diagnostic tool in the damage detection and also the patch location plays a significant role in the damage detection.
