3-D movement simulation techniques using FE methods: Application to eddy current non-destructive testing

A Model Assisted Probability of Detection Approach for Ecndt of Hidden Defect in Aircraft Structures

“…Before addressing the work on the estimation and evaluation of the probability of detection, we will devote this part to the modeling of a riveted structure by exploiting the results obtained from eddy current sensors in absolute mode. Several researchers have developed both analytical and numerical approaches in order to develop this direct model by calculating the necessary quantities including impedance calculation, reaming and alteration of the model by a defect [16,19]. The proposed model had to be able to take into account the multilayer configuration of the riveted structure with a variation in the properties of each layer of the structure under test.…”

3D surface crack characterization by eddy current array image and a fast algorithm search

“…Alternatively, to achieve an acceptable accuracy, the population size must be increased what induce a significant computation time. As a result, the proposed method is more preferred; because it is faster and its performance does not change when the calculation is reset, which is not the case for the other stochastic methods [17,18]. Therefore, the following figure summarizes the different steps for 3D crack reconstruction.…”

Efficient finite element modelling of eddy current probability of detection with transmitter–receiver sensors

“…Different meshing techniques to handle the movement of the sensor are described in [18]. In [19] a reduced formulation for the magnetic and electric potentials was developed.…”
