“…A proposal to introduce a hysteresis model into magnetic field distribution equa tions is described in [17]. In some approaches for modeling the magnetization process, th domain structure is used to represent changes in the magnetic flux density [18][19][20][21][22][23]. How ever, a method to determine the changes in the flux density for any magnetization direc tion has not been devised.…”

Magnetic fields in transformer cores are typically assumed to be one-dimensional fields, thus allowing magnetization processes to be regarded as axial magnetization. However, in the core corners or T-joint points of medium- and high-power rating transformers, the magnetic lines have different directions with respect to the rolling direction. This paper describes a method that allows changes in the flux density of transformer steel sheets to be calculated for any magnetization direction. These changes are assumed to depend only on certain limiting hysteresis loops assigned separately to the rolling and transverse directions of a tested transformer sheet, where these loops depend on the magnetization direction on the sheet plane. The selection of coefficients that define the limiting hysteresis loops for several magnetization directions is described, and the condition for the flux density saturation is considered. The resultant flux density in a specified magnetization direction is the geometric sum of the corresponding flux densities assigned to both the rolling and transverse directions. The limiting and partial hysteresis loops determined based on the proposed method for several magnetization directions are compared with analogous measured loops. Additionally, a comparison of the calculated hysteresis loops with loops showing changes in the resultant flux density for several magnetization direction is presented.

“…In order to calculate the effect of stress on the magnetic shielding performance of magnetic shielding devices, it is necessary to establish a model of the magnetic properties and stress of permalloy, which could make the simulation results of the residual magnetic field, uniform zone, and demagnetization of the magnetic shielding device more accurate. The most widely used model in modeling the magnetic properties of soft magnetic materials is the Jiles Atherton (JA) model [16,26,27]. Sablik et al [28,29] studied the consideration of magnetoelastic effects in modeling hysteresis loops.…”

The magnetic shielding devices are extensively used in measurement of quantum physics, the static magnetic field shielding layer made of permalloy in the magnetic shielding device will work under different stresses. Due to the magnetic properties of permalloy is sensitive to the applied stress, it is necessary to establish a magnetic property model considering stress to accurately evaluate the residual magnetic field in magnetic shielding devices under different stresses. However, the measurement and modeling of the magnetic properties of permalloy under different stresses have not been considered in relevant research. In this paper, the magnetic properties of permalloy under different tensile and compressive stresses were measured, and the optimized Jiles-Atherton model of permalloy considering stress is constructed. The parameters of J-A model are extracted by genetic algorithm-particle swarm optimization algorithm (GA-PSO) through measurement. Finally, the effectiveness of the model in predicting magnetic properties is validated. The Jiles Atherton optimization model considering stress can improve the calculation accuracy of magnetic shielding devices, which is of great significance for the design and application of magnetic shielding devices.

“…The last class of magneto-mechanical hysteresis models consists of a combination approach: the reversible behavior is modeled with a magneto-mechanical multiscale approach, and the magnetic hysteresis is considered from a macroscopic description. In this case, examples are the combination of the full multiscale approach and Hauser model [30], the SMSM with the magnetic JA model [22] [31] [32], and the analytical multiscale model with the Kádár product model [33] or with the JA model [34]. Hysteresis effects are considered in the Armstrong model by defining a macroscopic energy dissipation term related to the defects of a material, which constraints the domain wall motion [35].…”

The influence of mechanical stress on the magnetic hysteretic behavior is modeled through the association of a reversible simplified multiscale approach, and a macroscopic energy-based magnetic hysteresis model in a vector-play form. A phenomenological description of the dissipation parameters under mechanical stress is proposed. The non-monotonic effect of tensile stress on the magnetic permeability is modeled using a second-order development in the magneto-elastic energy. Material parameters for both reversible and irreversible behavior are identified from experimental characterization under mechanical stress performed on a DC04 electrical steel. The experimental tests include anhysteretic and hysteretic measurements. Modeling results of the anhysteretic magnetic permeability, the coercive field, and the remanent induction under several levels of peak magnetic field and uniaxial mechanical stress are satisfactorily compared with those obtained experimentally. The model is shown to reasonably predict the hysteresis losses under tensile and compressive stress, as well as the response of the material under a complex magnetic field waveform with harmonic content.INDEX TERMS Hysteresis model, magneto-elastic behavior, multiscale modeling, electrical steel.
