Simulation on the Directional Characteristic of Rectangular Probe Using Pulsed Eddy Current Testing

Pulsed eddy current (PEC) testing technology is an emerging electromagnetic nondestructive testing technology. There are certain restrictions on detection of anisotropy of metal materials using pulsed eddy current circular probe. However, the rectangular probe has some advantages. The finite element model of rectangular probe using COMSOL is built. The directional characteristics of the rectangular probe are simulated based on horizontal and perpendicular locations. The results show that the directional characteristics are obvious. The conclusion will provide some references on defect and stress detection by rectangular probe.
