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

Highly effective system for excitation and reception of Lamb waves in ferromagnets

The paper presents the concept of a highly efficient system for excitation and reception of Lamb waves in ferromagnets. Methods for creating large polarizing fields allowing to increase the efficiency of generation and reception of Lamb waves in ferromagnets and the principles of unidirectional electromagnetic-acoustic transducers are proposed. The results obtained in this work can be used in the development of devices for non-destructive testing of the long ferromagnetic objects. © Published under licence by IOP Publishing Ltd

DETERMINING THE APPLICATION AREA OF THE TECHNIQUE FOR SOLVING THE INVERSE GEOMETRIC PROBLEM OF MAGNETOSTATICS FOR SURFACE DEFECTS OF A FERROMAGNET

Magnetic flux in a ferromagnetic plate containing a defect under its tangential magnetization is considered. Magnetic flux is the key that determines the size of defects for which the inverse geometric problem can be solved by present methodology. Results of numerical experiments are presented.Работа выполнена в рамках государственного задания по теме «Диагностика», № AAAA-A18-118020690196-3
