Damage detection in structures using electromechanical impedance and finite element analysis

Damage detection in structures using electromechanical impedance and finite element analysis

Impedance-based structural health monitoring (SHM) techniques have been developed as a promising tool for real-time structural damage assessment, and are considered as a new nondestructive evaluation method. It is gaining popularity due to its potential of reducing maintenance costs while increasing...

description Impedance-based structural health monitoring (SHM) techniques have been developed as a promising tool for real-time structural damage assessment, and are considered as a new nondestructive evaluation method. It is gaining popularity due to its potential of reducing maintenance costs while increasing safety and reliability.

Modeled structure was excited to vibrate at high frequency range and electromechanical impedance (EMI) plots were obtained from the harmonic analysis. Notches were introduced in the beam and the damage metrics were used to assess qualitative changes in structural properties of the system.
