| Résumé | Current industry requirements demand defect quantification rather than simple defect detection. Besides the defect geometrical size, its depth location plays a critical role for the integrity of a structure and the safe life operation of the overall assembly. It has been long known that pulsed eddy current (PEC) non-destructive testing (NDT) for electrically conductive materials has the advantage of gathering different depth information in a single excitation process. This fact is due to the low frequencies found in the pulse spectrum that is used for the excitation of the driving coil; however, quantifying the defect depth still remains a challenge. This study considers different pulse widths and frequency components as a method of defect depth discrimination with direct applications in the evaluation of corrosion defects in multi-layer aircraft structures. Experimental testing and numerical modelling approaches are concomitantly discussed as ways of defect depth quantification. |
