An integral equation model for the magnetic flux leakage method

This paper describes a new method for the calculation of the MFL field from a given defect shape and induced magnetisation. The field is described by means of three-dimensional integral equations, providing a view similar to a standard MFL corrosion detection tool. This method allows the quick calcu...

Zusammenfassung:	This paper describes a new method for the calculation of the MFL field from a given defect shape and induced magnetisation. The field is described by means of three-dimensional integral equations, providing a view similar to a standard MFL corrosion detection tool. This method allows the quick calculation of the MFL field on a standard PC.
