Eddy current nondestructive evaluation – the challenge of accurate modeling
Abstract:
Eddy current nondestructive testing (EC NDT) has been used in industry and particularly in the nuclear power generation industry for over 30 years with mixed results. Whereas the method is robust, it has been plagued by problems of accurate interpretation of results. Computational electromagnetic methods have in the past provided some guidance to testing but were unable to accurately model and interpret the results. Current attempts in modeling based on finite elements in conjunction with surface impedance boundary conditions and accurate modeling of motion are shown to be much more effective in resolving this long-standing issue. The methods espoused apply well beyond eddy current NDT.
Nathan IDA is Distinguished Professor of Electrical and Computer Engineering at The University of Akron in Akron, Ohio, USA. His current research interests are in the areas of numerical modeling of electromagnetic fields, electromagnetic wave propagation, theoretical issues in computation, nondestructive testing of materials at low and microwave frequencies as well as in communications, especially in low power remote control and wireless sensing. Dr. Ida has published some 250 papers on electromagnetic field computation, parallel and vector algorithms and computation, nondestructive testing of materials, surface impedance boundary conditions, electromagnetic and microwave sensors and others. He has written six books, two on computation of electromagnetic fields a third on nondestructive testing with microwaves, a textbook on electromagnetics, now in its second edition, a monograph on surface impedance boundary conditions and a textbook on sensors and actuators. Born in Romania in 1949, he received his BSEE and MSEE from the Ben Gurion University of the Negev in Israel in 1977 and 1979 respectively. In 1983 he received his Ph.D. in Electrical Engineering from Colorado State University in Fort Collins, Colorado.
