A novel estimation model for hysteresis loss based on semi-minor loops

open access: yesEnergy Reports, 2022
This paper proposes an estimation model of hysteresis loss based on the mapping of the hysteresis loop conducted through tiny material samples with the aid of the Superconducting Quantum Interference Device (SQUID).

Calculation of core hysteresis loss resistance for Buntenbach’s analogy hysteresis model

open access: yesAIP Advances
The value for core hysteresis loss (CHL) resistance in Buntenbach’s analogy hysteresis model does not consider the impact of frequency variations. In order to address this issue, this paper proposes a calculation expression for CHL resistance that takes ...

Rolling Tires on the Flat Road: Thermo-Investigation with Changing Conditions through Numerical Simulation

open access: yesApplied Sciences, 2023
A crucial material comprising a pneumatic tire is rubber. In general, the tire, or more specifically, the hysteresis effects brought on by the deformation of the part made of rubber during the procedure, heat up the part.

An Improved Approach to Calculate Eddy Current Loss in Soft Magnetic Materials Based on Measured Hysteresis Loops

open access: yesEnergies, 2022
The paper presents a study of the influence of magnetic hysteresis on macroscopic eddy current losses. Usually, this loss is calculated within many simplifying assumptions, of which the most striking is not only neglecting the hysteresis, but also the ...

Expression for hysteresis loss of immobilized magnetic nanoparticles in a wide range of particle parameters and excitation conditions: Parameter optimization for hyperthermia application

open access: yesAIP Advances, 2021
Hysteresis loss of magnetic nanoparticles (MNPs) has been widely studied for magnetic-hyperthermia application. On the basis of the numerical simulation for the AC magnetization curve of immobilized MNPs, we obtain an analytical expression for the ...
