Paper Abstract

Crack monitoring plays a great role in modern structural health monitoring. A new scheme of the sensor is developed in this paper. The finite element model (FEM) of the sensor was established, and the output characteristics of the sensor were analyzed by FEM. It was shown that the sensor was sensitive to cracks, and could be used to monitor the propagation of cracks initiating from the edge of the hole. Finally, the sensor was prepared on a specimen, and the feasibility of the sensor to monitor cracks was demonstrated by experiment.
