Rigorous definition of Hysteresis

That is hysteresis. Hysteresis is the dependence of the state of the system on its history. What this should really say is that the time evolution of the system depends on its history. This is to contrast things like classical mechanics, where all you need to know is the current state of the system to know how it will evolve.

The high efficiency and low-toxicity are the two main objectives for all perovskite solar cells (PSCs) towards large scale commercialization. Herein, ecology-benign Zn was introduced to partially replace the noxious Pb in the typical Pb-based perovskite absorber layer owing to its low-toxicity, high-richness in the crust, suitable valence states, and good stability …

Effects of Hysteresis on TecsPak® Performance

Miner Elastomer Products has released a new technical paper from our engineering team regarding the effects of hysteresis on TecsPak. One key advantage with TecsPak is that like most rubbers and elastomers, we have hysteresis which provides a certain level of damping. In fact, compared to most elastomers, TecsPak has a greater amount of …

Contact angle hysteresis

Static contact angle hysteresis is caused by roughness and heterogeneity. Surface features lead to pinning of the contact line and thus to an increase of the apparent advancing and a decrease of the apparent receding contact angle. In addition, surface adaptation and deformation can lead to changes in apparent contact angles.

The origin of hysteresis and memory of two-phase flow in

Quasistatic hysteresis is the macroscale manifestation of micro-scale energy-dissipative events along this evolution. It is also associated with history dependence, or memory, which reflects the ...

Hysteresis | Magnetic, Temperature & Stress

Hysteresis, lagging of the magnetization of a ferromagnetic material, such as iron, behind variations of the magnetizing field. When ferromagnetic materials are placed within a coil of wire carrying an …

Demystifying Hysteresis With Solenoid Control

Solenoid control offers a predictable output flow that adjusts pump displacement independent of hysteresis. This control utilizes an algorithm in a controller that takes the input command and compares it against the current displacement of the pump provided by the swash feedback sensor. The controller provides current to the …

[PDF] Sliding Crack Model for Nonlinearity and Hysteresis in …

Under triaxial deviatoric loading at stresses below failure, rocks generally exhibit nonlinearity and hysteresis in the stress‐strain curve. In 1965, Walsh first explained this behavior in terms of frictional sliding along the faces of closed microcracks. The hypothesis is that crack sliding is the dominant mode of rock inelasticity at moderate …
