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.

1. Introduction. The definition of hysteresis is rather broad and context dependent. With its Greek root meaning lagging behind, the term "hysteresis" was first used in magnetism by Ewing (1885) to describe the lagged thermoelectric characteristics of a wire under different stress conditions. Since then, this term has been used to describe …

Uniaxial compression tests on rocks, if conducted at stresses below failure, typically exhibit both non-linearity and hysteresis in the stress–strain curve. In a series of three papers in 1965, Walsh explained this behavior in terms of frictional sliding along the faces of closed cracks. Although well known and widely cited, Walsh's model does not …

Figure 5 illustrates the output of a comparator with hysteresis with a noisy input signal. The input must transition above the upper threshold (VH = 2.7V) for the output to transition to logic low (0V). The input must also transition below the lower threshold for the output to transition to logic high (5V).

Magnetic Hysteresis. A magnetic hysteresis, otherwise known as a hysteresis loop, is a representation of the magnetizing force (H) versus the magnetic flux density (B) of a ferromagnetic material. The curvature of the hysteresis is characteristic of the type of material being observed and can vary in size and shape (i.e. narrow or wide).

Few studies have examined C–Q relationships in a surface mining context. Bonta used C–Q regressions to analyze three mining-influenced streams in Ohio, USA, and found significant relationships between streamwater chemical concentrations and discharge during the pre-disturbance and post-mining phases.Murphy et al. analyzed …

A hysteresis loop, also known as a hysteresis or magnetization curve, is a graphical representation of the hysteresis behavior. It illustrates the relationship between the magnetic flux density and the externally applied magnetic field strength. The flux density is plotted along the vertical axis. It is represented by the symbol B and has the ...

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 hysteresis. As is typical with most elastomers, when they are compressed there is internal friction that generates heat.
