What is meant by hysteresis effect?
What is meant by hysteresis effect?
Effects. Hysteresis Effect. The magnetization of ferromagnetic substances due to a varying magnetic field lags behind the field. This effect is called hysteresis, and the term is used to describe any system in whose response depends not only on its current state, but also upon its past history.
What is hysteresis effect in physical pharmaceutics?
Hysteresis is the dependence of a system on both its current and past environments. Figure 1c and d present the graphical evidence of a temporal relationship of dependence between the pharmacological effect and the drug plasma concentration.
What is hysteresis in biomechanics?
elastic hysteresis is a property of tendon and describes the energy dissipated due to material viscosity. The amount of tendon hysteresis is important for efficiency of locomotion. Higher hysteresis is associated with greater energy dissipation as heat, and thus less energy can be recoiled to propel our movements.
What is hysteresis explain with example?
Hysteresis is the dependence of the state of a system on its history. For example, a magnet may have more than one possible magnetic moment in a given magnetic field, depending on how the field changed in the past. Hysteresis can be found in physics, chemistry, engineering, biology, and economics.
What is hysteresis effect Slideshare?
Hysteresis: Definition : Hysteresis means “Lagging”. The lagging of intensity of magnetization (B) behind the intensity of magnetic field (H). Explanation : A graph is drawn between the intensity of Magnetization (B) and intensity of magnetic field (H).
What is the difference between creep and hysteresis?
These properties are creep, load relaxation and hysteresis: Creep describes the ability of a tissue to elongate over time when a constant load is applied to it. Hysteresis describes the amount of lengthening a tissue will maintain after a cycle of stretching (deformation) and then relaxation.
What is hysteresis in soft tissue?
When soft tissue is subjected to repetitive cyclic loading and unloading, the obtained stress–strain curves form hysteresis loops. These loops continually decrease over time of loading and then stabilize. Mechanical hysteresis is also associated with energy loss [2, 11].
What is hysteresis PPT?
1. Hysteresis: Definition : Hysteresis means “Lagging”. The lagging of intensity of magnetization (B) behind the intensity of magnetic field (H). Explanation : A graph is drawn between the intensity of Magnetization (B) and intensity of magnetic field (H).
What is the hysteresis effect?
The hysteresis effect arises in consequence of two competitive processes: (1) the sputtering of the target surface and (2) the covering of its surface by reaction products.
What is the difference between static hysteresis and creep effect?
The static hysteresis effect is typically coupled with the creep effect. The static hysteresis is rate independent. It is a strong nonlinearity and has global memories. Compared with the rate-independent static hysteresis effect, the creep effect has slow dynamics.
What is the hysteresis effect of a pump?
The hysteresis effect occurs if the system is unstable. It was found that the solution of Eq. (3.1) is stable under the following condition: where Sc is the critical pumping speed of the pumping system. This means that the hysteresis effect can be eliminated if SRG of the pumping system is greater than a critical value of Sc defined by Eq. (3.2).
How is the hysteretic dynamics model derived?
The hysteretic dynamics model is derived from the material, electrical, and mechanical fields. The complete modeling of the hysteretic dynamics consists of the static Preisach hysteresis, the creep effect, and electrical and vibration dynamics.
