چکیده
1 Recent progress in the application of the electro-mechanical (E/M) impedance method to structural health monitoring, damage detection, and failure prevention is presented. A brief review of the E/M impedance method principles is followed by applications to bolted and spot-welded structural joints, and to polymeric composite overlays to construction engineering structures. The modeling of the interaction between the piezoelectric active sensor and the host structure is described. The development of a meaningful structural damage index that can identify the damage presence, location, and magnitude is treated, and several recent works, including neural networks approach, are cited. Conclusions and suggestions for further work, and relevant bibliography are included.
