Hysteresis

Used to characterize a lagging effect. Firms may fail to enter markets that appear attractive, or firms that are once invested in a market may persist in operating at a loss. The effect is characteristic of investments with high entry and exit costs along with high uncertainty.

Hysteresis

In economics, a situation or indicator that persists despite evidence that it should not. For example, the unemployment rate tends to remain high even after GDP growth has resumed, in part because business owners are afraid that growth will turn negative again even if they have no rational reason for believing so. One may think of hysteresis as an economy's collective memory. See also: Lagging indicator.

It is understood from Figure 5(b) that the function [rho](u) is able to form the shape of hysteresis loop depending on the longitudinal velocity.
Figure 13 depicts the hysteresis loops according to the parameters obtained.
In above equation [E.sub.D] stands for the dissipated energy in hysteresis loop, [E.sub.E] for the elastic strain energy, [E.sup.+.sub.E] and [E.sup.-.sub.E] for the elastic strain energy in positive and negative direction of force action, [K.sub.p] and [K.sub.n] for secant stiffness of the loop in positive and negative direction, and [d.sub.max] and [d.sub.min] for the maximum and minimum displacements of the considered loop.
The variation of parameter [beta] for A = 1, [gamma] = 1, n = 1 has the effect of turning the backbone of hysteresis loop in clockwise simultaneously with its curving clockwise for negative values of the parameter [beta] and clockwise for positive values of the same parameter.
This can be seen in Figure 11 that shows the hysteresis loops at 100 cycles and 500,000 cycles for all materials investigated here.
The isotherms are type IV and exhibit hysteresis loops with well-defined adsorption and desorption branches.
When a material crystallizes and melts during a cyclic deformation, the material produces a substantial hysteresis loop: The hardening induced by crystallization during stretching is re covered during unloading.
Typical hysteresis loop of connection between steel plates and vertical member having pretension equals to 0 kN is shown in Figure 3.a.
The adsorption and desorption isotherms form a wide hysteresis loop. During adsorption, the pores with the diameter larger than the diameter of the nitrogen molecules are accessible to the penetrating nitrogen vapor regardless of the connectedness and arrangement of the pores.
The frictional hysteresis loop can be represented by the resulting elastic stiffness CT for the sticking contact condition (Fig.
