Hysteresis loss subdivision
(ELSEVIER SCIENCE BV, 2008)
Assuming that different energy dissipation mechanisms are at work along hysteresis, a hysteresis loss subdivision procedure has been proposed, using the induction at maximum permeability ( around 0.8 T, in electrical steels) ...
Estimating hysteresis in the soil water retention curve from monolith experiments
(2012-11-01)
Water movement in unsaturated soils is commonly affected by hysteresis, a phenomenon often ignored as to keep the mathematical description of water flow and solute transport simple. In this study, the importance of hysteresis ...
Cauchy-Stieltjes Integral on Time Scales in Banach Spaces and Hysteresis Operators
(Amer Inst Physics, 2012-01-01)
The play operator has a fundamental importance in the theory of hysteresis. It was studied in various settings as shown by P. Krejci and Ph. Laurencot in 2002. In that work it was considered the Young integral in the frame ...
Two simple techniques for hysteresis power losses measurement
(IEEE, 2007-01-01)
This paper presents two methods to measure magnetic losses in an iron core for didactic applications for undergraduate students. It is based on indirect measurements of magnetic field and induced flux, simplifying the ...

Subdivision of Hysteresis Loss in Mn-Zn Ferrite Toroidal Cores
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
The hysteresis loss subdivision method proved to be a strong tool to help in the analysis of different energy dissipation mechanisms along the quasi-static hysteresis loop measured on electrical steels. This paper used the ...
Limiting loop proximity hysteresis model
(2003-01)
This paper introduces a simple algebraic limiting loop proximity ((L2P)) model to describe magnetic hysteresis. With only four parameters, it has low computational cost and reduced mathematical complexity, thus permitting ...
Simple hysteresis loop model for rock magnetic analysis
(Springer, 2020-01)
A simple phenomenological model founded on Lorentzian functions is evaluated on the first derivative of magnetic hysteresis loops from several artificial samples with iron oxide/oxyhydroxide mixtures imitating natural ...
