“…Kikuchi et al [31] examined the feasibility of NDT evaluation of magnetic properties and hardness of two-layered specimens by magnetostatic single-yoke probes. In spite of using a 2D approach in a simulation, they observed a good correlation between experimental and FEA-derived initial magnetisation curves for layered plates.…”

The paper contains an original comprehensive review of finite element analysis (FEA) applied by researchers to calibrate and improve existing and developing electromagnetic non-destructive testing and evaluation techniques, including but not limited to magnetic flux leakage (MFL), eddy current testing, electromagnetic-acoustic transducers (EMATs). Premium is put on the detection and modelling of magnetic field, as the vast majority of ENDT involves magnetic induction, either as a primary variable MFL or a complementary phenomenon (EC, EMATs). FEA is shown as a fit-for-purpose tool to design, understand and optimise ENDT systems, or a Reference for other modelling algorithms. The review intentionally omits the fundamentals of FEA and detailed principles of NDT. Strain-stress FEA applications in NDT, especially in ultrasonography and hole-drilling methodology, deserve as well a separate study.

“…Due to the fact that many parameters of the limiting hysteresis loop and the magnetization curve are sensitive, including to the stress-strain state, it is possible to establish a correlation between internal stresses and magnetic properties [8]. However, when establishing a regression equation, a linear function is generally used.…”

This article presents the results of the steel products properties research through non-destructive testing, based on the dependence of mechanical properties on magnetic ones. The objective of the research was to increase the accuracy of determining the mechanical properties of steel products in a non-destructive way through the use of a polynomial dependence. The correlations used in this work were obtained using regression analysis in Excel. The reliability of increasing the accuracy of determining mechanical properties through the structure-sensitive parameters of the magnetic hysteresis loop (coercive force, maximum magnetic permeability and residual magnetic induction) using a polynomial dependence is confirmed by experimental data. The output parameters of the regression equations were the basic mechanical properties: tensile strength, yield strength and elongation. The use of a polynomial dependence, compared to a linear one, made it possible to reduce the error in determining the properties of steel products from 4 % to less than 1 %. Keywords: polynomial dependence, non-destructive testing, mechanical properties, regression, error.

"В данной работе исследованы магнитные свойства стали 13ХФА с целью возможности проведения неразрушающего определения значений механических свойств. Проведен анализ существующих способов неразрушающего контроля механических свойств и обоснована перспективность применения магнитного способа определения механических свойств вместо стандартного разрушающего – испытание на растяжение, а также приведены преимущества магнитного способа определения перед другими неразрушающими, таких как тепловой и механический, в которых применяется измерение теплопроводности и твердости по Бринеллю соответственно. Определено влияние изменения прочностных свойств на величину магнитных показателей, для чего на стальных образцах была проведена закалка с последующим отпуском при температурах 500, 550, 600, 650 и 700 °С. Обосновано уменьшение коэрцитивной силы и увеличение остаточной магнитной индукции и максимальной магнитной проницаемости при отпуске стали от 500 до 650 °С, а также выявлена причина их изменения в обратную сторону. Даны рекомендации по выбору магнитных характеристик для неразрушающего контроля их структурного состояния. Выявлена немонотонность изменений значений магнитных свойств и обоснованы экстремумы кривых диаграмм, связанных с изменением структуры отпущенной стали. "
