Width of the hysteresis loop
was calculated using Eq.
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.
The hysteresis loops
at these two locations are shown in Fig.
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.
