Stress-Induced Magnetic Signals for Structural Health Monitoring of Civil Infrastructures
In this research, the correlations between the magnetic signals and the mechanical behavior of a ferromagnetic steel structure under tensile loads were investigated. The failure mode of the tested steel joint was the buckling of the annular plate. It was observed that during the loading process the piezomagnetic response demonstrated a different behavior compared to the mechanical response. The greater variation of the load-B field curve shows that piezomagnetic signal is a more sensitive indicator of structural failure than the mechanical response. The piezomagnetic effect may be used as a promising method to monitor the failure process of civil infrastructures.
