Analysis of a Nondestructive Evaluation Technique for Defect Characterization in Magnetic Materials Using Local Magnetic Measurements
Figure 10
Results of the inverse problem for a sample with multiple strips. The artificial measurement points are plotted together with the akima interpolant and the surface magnetic induction at the optimal configuration. (a) Nonoverlapping gaps, 41 measurements, 5% noise. (b) Overlapping gaps, 41 measurements, 5% noise. (c) Non-overlapping gaps, 21 measurements, 5% noise. (d) Non-overlapping gaps, 21 measurements, 10% noise.
