The hysteresis loop, described during the formation of stressinduced pseudoelastic martensite in a Cu-Zn-A1 betaphase single crystal, was studied as a function of strain-rate, deformation amplitude and temperature. The aPtm, the stress at which the transformation starts at a given constant temperature, is strain-rate independent but the hysteresis described by the stress-strain curve shows a ma...

One of the most important remaining issues in the theory of hysteresis is a complete description of the physical meaning of the parameters that define the model equations.’ In common with the Stoner-Wohlfarth theory of rotational processes, the theory of hysteresis provides one of the few theories of hysteresis based on underlying physical mechanisms, rather than curve fitting models. In this p...

Data obtained from modified cone penetrometer experiments were used to estimate the hysteretic soil hydraulic properties with a parameter estimation technique which combined a numerical solution of the Richards equation with Marquardt-Levenberg optimization. The modified cone penetrometer was designed to inject water into a soil through a cylindrical screen, measure the infiltration rate with t...

This paper is a phenomenological study representing the influence of hardening type on instrumented indentation F-h curve. Spherical and inverse analysis techniques (IAT) are used two metallic materials (DP600 AA2017) investigated. Pure isotropic (Voce) combined (Chaboche 1986) laws adopted for describing plastic behavior studied materials. The loading curve first. Kinematic results in softenin...

An electrode in a lithium-ion battery may undergo inelastic processes of two types: flow and reaction. Flow changes the shape of the electrode, preserves its composition and volume, and is driven by the deviatoric stress — a process similar to the plastic flow of a metal. By contrast, reaction changes the composition and volume of the electrode, and is driven by a combination of the mean stress...
