title = "Rapid estimation of artificial near-side crack dimensions in aluminium using a GMR-based eddy current sensor",
abstract = "This paper presents a method for rapid quantification of long artificial cracks using a GMR-based eddy current sensor. The quantification is achieved simultaneously through a proposed phenomenological relationship between the cracks dimension and two parameters extracted from the GMR output signal. The results show that the proposed method is valid and advantageous when a quick and reliable estimation of the cracks dimension is necessary. A criterion taking into consideration the filling factor of the excitation coil is proposed in order to improve the systems sensitivity.",
