文摘
- •
An electromechanical impedance (EMI) technique based on mechanical impedance was proposed.
- •
The structural mechanical impedance (SMI) was theoretically derived from the EMI model.
- •
An experiment of monitoring corrosion damage progression on a steel beam was implemented.
- •
The sensitivity of SMI was investigated qualitatively and quantitatively.
