A mechanical impedance approach for structural identification, health monitoring and non-destructive evaluation using piezo-impedance transducers

This research has focused on utilizing the underlying PZT-structure electro-mechanical interaction for an impedance based structural identification and SHM/ NDE using the EMI technique. A new concept of active signatures has been introduced to extract the damage-sensitive information from the raw si...
