Description

The numerical modeling of single frequency eddy-current phenomena based on the magnetic vector potential has been successfully applied to many NDT applications [1–3]. Despite the considerable wealth of sinusoidal eddy-current literature, the numerical modeling of pulsed eddy-currents has received little attention. Most of the recent finite element transient eddy-current NDT modeling [4,5] employs a variational time-domain formulation for 2D and axisymmetric geometries. Since this model was tested against experimental measurements, it lacks rigorous quantitative verification required to be a useful NDT design tool.
