Transient Eddy Current Analysis of Pulsed Eddy Current Testing by Finite Element Method

Fast analytical modelling for pulsed eddy current evaluation

“…After the time-stepping solver was introduced in FEM, 2D and 3D FEM simulations are commonly used to PEC problems. Tsuboi et al proposed 2D and 3D FEM models to analyse the PEC response to a flawed plate and the TEAM Workshop Problem 27 [5]. Good agreement between FEM results and measured values can be achieved.…”

Transient Eddy Current Response Due to a Subsurface Crack in a Conductive Plate

“…In finite element scheme, the differential equation defining the magnetic vector potential and electric scalar potential are transformed into algebraic matrix equations. [9] was developed to calculate the transient magnetic field due to a half space conductor. The edge elements are vector finite elements whose tangential component is continuous at the interface of two adjacent elements, but jump is allowed for the normal component.…”

Quantitative non-destructive evaluation of wall thinning defect in double-layer pipe of nuclear power plants using pulsed ECT method

“…The PECT method has features of non-contact between the probe and the inspected target, application of large excitation currents and rich frequency components [5][6][7][8][9][10][11][12][13]. Recently, a high efficiency 3D numerical tool (a fast forward solver) to predict PECT signals has been developed [14] by authors.…”
