摘要
Semi-analytical solution of eddy current testing problem is presented in the paper. An excitation air-core coil is located above a conducting plate with two flaws in the form of cylindrical holes located at top and bottom parts of the plate. The change in impedance of the coil is computed for different frequencies of the excitation current. Potential applications (analysis of the effect of corrosion, estimation of thickness and conductivity of metal coatings and quality testing of spot welding) are discussed.
