| Abstract: | On the base of the magnetic charge dipole theory, the relation of the magnetic leakage field strength and the microcrack size is analyzed for type V microcrack, and a mathemat-ical model is set up for describing the relation of the normal component of the magnetic leakage field with the width and the depth of the microcrack. From experiments, it is demonstrated that the mathematical model has a fairly high accuracy, hence forming a basis for the quantitative analysis of the microcrack signal. |
