摘要：
We propose a new nondestructive method for the magnetic diagnostics of ferromagnetic thin-walled structures based on the analysis of acoustic-emission signals. The distribution of the magnetic field induced in a ferromagnetic half space by a magnetic dipole located over the surface of this half space is determined. The diagrams of dependence of the stress intensity factor on the location of a disk-shaped crack in the material are constructed.
