[‚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.
