On the inverse problem of magnetostatics

This work is devoted to solving the inverse problem of the magnetic method for nonde- structive testing (MMNDT). The purpose of the work, frankly speaking and avoiding complicated concepts and formulas, is to identify research directions in MMNDT that would approach solution of the inverse problem in the field of magnetic defectoscopy to the highest extent. © 2013 Pleiades Publishing, Ltd

Main features of distributions of the magnetic flux leakage fields of defects different shapes

The features of topography of the magnetic fields of various defects are considered using the finite element method (FEM). The distinctive attributes of these defects are identified and some recommendations are given on determining different types of defects. It is shown that extremes of the normal component of the magnetic field created by defects are closely connected with an orientation and an angle of inclination of a defect in a plate. An approach for estimating this angle of inclination of surface defects and extended subsurface defects is proposed. © Published under licence by IOP Publishing Ltd.Ministry of Science and Higher Education of the Russian FederationThe research was carried out within the state assignment of Ministry of Science and Higher Education of the Russian Federation (theme «Diagnostics» No. АААА-А18-118020690196-3)
