Modeling of hysteretic behavior in ferroelectric polymers
Journal of Polymer Science Part B: Polymer Physics, 2015Controlling the polarization state of ferroelectric materials, and more particularly piezoelectric polymers, is critical to ensure good operation of actuators or sensors using such energy conversion mechanisms. More specifically, the modeling and prediction of the hysteretic behavior of such materials is a critical aspect for the fabrication of robust ...

Pseudo-hysteretic behavior in semiconductor-superconductor junction
Physica C: Superconductivity, 2000Abstract A recent work by Th. Schapers et alli [1] showed the coupling to a superconductor of the two-dimensional electron gas in a doped semiconductor heterostructure. The presented I–V characteristic exhibits a hysteresis at the low-voltage range, similarly to I–V curves of other works for analogous structures.

Control of hysteretic behavior in flux concentrators
Applied Physics Letters, 2009The magnetic states of flux concentrators (FCs), consisting of poles and yokes with lateral dimensions in the range of 100 μm and integrating either single layer films of amorphous alloys of Cox(Zr–Nb)1−x with x=90 and x=88 or a synthetic antiferromagnet (SAF) of (NiFe/Ru)xn, are analyzed by Bitter pattern and magnetic force microscopy.

Hysteretic Behavior of Superfluid Helium in Anopore
Journal of Low Temperature Physics, 2000Superfluid 4 He exhibits hysteretic behavior due to capillary condensation in Anopore, a porous membrane containing mostly non-intersecting cylindrical pores. Because the pores are non-intersecting, we expect the system may behave similarly to a system of nearly non-interacting spins, where spin-up is equivalent to a filled pore and a spin-down is ...

Ion-Gel-Gated Graphene Optical Modulator with Hysteretic Behavior
ACS Applied Materials & Interfaces, 2018We propose a graphene-based optical modulator and comprehensively investigate its photonic characteristics by electrically controlling the device with an ion-gel top-gate dielectric. The density of the electrically driven charge carriers in the ion-gel gate dielectric plays a key role in tuning the optical output power of the device. The charge density

Hysteretic behavior using the explicit material point method
Computational Particle Mechanics, 2018The material point method (MPM) is an advancement of particle in cell method, in which Lagrangian bodies are discretized by a number of material points that hold all the properties and the state of the material. All internal variables, stress, strain, velocity, etc., which specify the current state, and are required to advance the solution, are stored ...

Modeling and compensation of piezoelectric ceramic hysteretic behavior
2009 International Conference on Mechatronics and Automation, 2009Piezoelectric actuators are widely applied as actuators in micro/nano-positioning systems, due to its characteristic of infinitely small displacement resolution. While the tracking control accuracy of the piezoelectric actuator is limited because of their inherent hysteretic nonlinearity.

Scaled Memory Description of Hysteretic Material Behavior
Journal of Applied Mechanics, 1996Herein the concept of scaled memory (SM) is proposed to describe hysteretic material behaviors. SM scales the nonlinear variation of tangential modulus during monotonic loadings into a piecewise linear distribution, which can easily be modified to simulate specific characteristics of material behavior during cyclic loadings.

Analysis of Hysteretic Behavior of Anchored Reinforcing Bars
1997This paper presents the analysis of the hysteretic behavior of anchored reinforcing bars with a new finite element model. The Smile element is based on the interpolation of the steel stress distribution and thus, is flexibility-based. It is characterized by robust and stable numerical behavior even in the presence of significant strength loss and ...
