Description

An experimental modeling technique based on the use of liquid mercury samples containing artificial discontinuities has been examined to establish the applicability of this approach to the assessment of eddy current inspection capabilities. Results show that the mercury modeling concept provides an accurate, rapid and inexpensive approach to the calibration and characterization of eddy current inspection techniques. Data are presented which clearly show the impact of defect size, type and location on the eddy current response developed with a surface riding “pancake” probe. The potential of mercury modeling to enhance the understanding of eddy current inspection techniques and also to guide the development of rational analytical modeling is discussed.
