Abstract

In pulsed eddy current testing (ECT), much information can be obtained by a measurement. Understanding the electromagnetic phenomena in pulsed ECT is necessary for establishment of the design method of probe and the processing method of detected signal. In this paper, a simple axisymmetric aluminum plate model was investigated by using finite element analysis. We tried to clarify the electromagnetic phenomena in the aluminum plate model excited by pulsed source current and collect fundamental data for the investigation of three-dimensional problems.
