摘要：

Pulsed eddy current non-destructive evaluation is concerned in the paper. Impact of eddy-current probe's configuration on response signals, especially on crack's depth resolution is numerically investigated. The induction coupling between a probe and a material affects information transfer between the probe and the material and consequently it influences the resolution of detected defects. Numerical simulations with various diameters of a coil are performed and evaluated to investigate impact of this parameter on resolution of defects with different depths.
