Numerical evaluation of correlation between crack size and eddy current testing signal by a very fast simulator

Adaptive inversion database for electromagnetic nondestructive evaluation

“…A comprehensive review of methods used for the solution of direct problems in ECT is presented in [11]. More specifically, a quite incomplete list of works describing the various methods for the analysis of the crack-probe interaction is [12][13][14][15][16]. In the present study we apply the method introduced in [3], which is in fact the numerical analysis of the so-called ''thin crack…”

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

“…Recently, a high efficiency 3D numerical tool (a fast forward solver) to predict PECT signals has been developed [14] by authors. This 3D code is based on a frequency domain computation scheme and employs a database strategy which is similar to that developed for the fast simulation of single frequency ECT signals [15][16][17]. The 3D code gives a good basis for the quantitative wall thinning analysis based on inversion techniques.…”

A Probabilistic Damage Identification Method for Shear Structure Components Based on Cross-Entropy Optimizations

“…Several non-destructive evaluation methods such as ultrasound inspection [7][8][9][10][11][12][13], eddy-current testing [14,15], and Lamb wave-based methods [16][17][18][19][20][21] can effectively identify local damages in a component. To identify the component damage on a global basis, capturing the changes in vibration characteristics of the entire structure is one of the few methods that can be applied in practice [22,23].…”
