hysteresis loop

[‚his·tə′rē·səs ‚lüp]
(physics)
The closed curve followed by a material displaying hysteresis (such as a ferromagnet or ferroelectric) on a graph of a driven variable (such as magnetic flux density or electric polarization) versus the driving variable (such as magnetic field or electric field).

From the hysteresis loops in the first 1-5th, 50th, 100th, and 200th cycles respectively, it can be summarized that (i) the loop of stress-strain curve and the ratcheting strain move along the direction of nonzero mean stress; (ii) the hysteresis loops become more and more narrow with the increasing number of cycles; (iii) the progressive accumulation rate of strain at valley is faster than that at peak (the details are illustrated in Fig.
To ease the comparison of the stiffness degradation, the secant stiffness of the hysteresis loop K was normalized with the effective stiffness [K.
This can be seen in Figure 11 that shows the hysteresis loops at 100 cycles and 500,000 cycles for all materials investigated here.
It is a series of hysteresis loops corresponding to each cycle of negative and positive deflections of the wall.
For magnetometric systems, a possible candidate must have a highly square hysteresis loop [m.
where [DELTA]T is the average temperature rise, w is the area inside the hysteresis loop, f is the testing frequency, and B is a material dependent constant.
Recorded stress-strain curves of the casing material appear in the shape of hysteresis loops and represent the performance of protein belkozin casings during the automatic filling it with the sausage mass.
The whole plant possesses nonlinear behavior because of the hysteresis loop determining the relationship between the input voltage and the rotation speed of the engine (Roubal, 2007).
This calculated parameter may be found in ASTM D5992 and assumes the hysteresis loop is a perfect ellipse.
