摘要:
This paper presents computational results of the second eddy current benchmark problem proposed by the World Federation of Nondestructive Evaluation Centers. The problem involves the prediction of the change in impedance of a pancake coil as it scans the inner surface of a metal tube along both the axial and circumferential directions for detection of flaws on the outer surface. A finite element scheme is carried. The real and imaginary part of the impedance is obtained by observing the total stored energy and the dissipated energy, respectively. © 2003 American Institute of Physics
