Experimental verification of 3D eddy current analysis code using T-method

An experimental verification of a 3-D eddy current analysis code based on the T-method was performed by applying it to an eddy-current testing (ECT) problem. Specifically, signal trajectories for ECT of a block with a flaw were measured. The experiment was performed for the ECT benchmark problem defined by the TEAM Workshops for two frequencies. Numerical results for 500 Hz and 1 kHz agreed well with measured values, demonstrating the validity of the method and the code for 3-D eddy-current problems. >
