The influence of stress on ferromagnetic hysteresis

IEEE Transactions on Magnetics, 1990
It is argued that attempts to describe the stress magnetization behavior of ferromagnetic materials have, in general, relied upon unsubstantiated assumptions regarding the distribution of domains and the relative motion of domain walls under the combined influences of applied field and mechanical stress.

A stress-dependent magnetic Preisach hysteresis model

IEEE Transactions on Magnetics, 1991
The authors present a generalization of the classical Preisach model which handles coupled magnetic and mechanical hysteresis. Magnetostrictive materials are known to have hysteresis with respect to both magnetic field H and mechanical stress lambda .

Rotational hysteresis model for stressed ferromagnetic films

IEEE Transactions on Magnetics, 1997
The effect of an external mechanical stress on the coercive force of Ni is different for bulk and for thin films. The bulk behavior is correctly explained by the Sablik-Jiles model which assumes that wall displacement is the driving mechanism of the magnetization process.

Hysteresis of Capillary Stress in Unsaturated Granular Soil

Journal of Engineering Mechanics, 2004
Constitutive relationships among water content, matric suction, and capillary stress in unsaturated granular soils are modeled using a theoretical approach based on the changing geometry of interparticle pore water menisci. A series of equations is developed to describe the net force among particles attributable to the combined effects of negative pore

THE HYSTERESIS LOOP 3. STRESS‐DIP EXPERIMENTS

Fatigue & Fracture of Engineering Materials & Structures, 1982
Abstract— A stress‐dip technique for the determination of an effective stress in cyclic straining has been improved. The critical stress drop, ΔσC, for which zero strain relaxation rate is observed can be obtained from experiments. The significance of this quantity is discussed in terms of the statistical theory of the hysteresis loop. The measurements

Stress relaxation and hysteresis at various strain rates

Journal of Applied Polymer Science, 1964
AbstractApplying the Boltzmann superposition principle on a generalized Maxwell model, an analysis of the relations between extension, relaxation, and hysteresis is presented, which shows that any one of these three can be calculated from the other two.

Rupture propagation in hysteresial materials: Stress at a notch

Journal of the Mechanics and Physics of Solids, 1963
Abstract Measurements have been made of stress concentration at notches in sheets of rubber displaying marked mechanical hysteresis. The notches represent model cracks and it is shown that when made in pre-stretched sheets they simulate the case of a propagating crack.

Hysteresis loop as the indicator of residual stress in drawn wires

Nondestructive Testing and Evaluation, 2014
The paper investigates the possibility of using the magnetic method for non-destructive determination of residual stress in drawn wires. The change in residual stress for different processing speeds is reflected in the shape of hysteresis loop. A simple model for stress-dependent hysteresis, based on the concept of the effective field, is proposed. The
