Pinched hysteresis
WebOct 29, 2024 · Abstract: Two existing theorems for studying pinched hysteresis loops generated by nonlinear higher-order elements from Chua's table are reformulated, namely the generalized homothety theorem and the associated Loop Location Rule, specifying the coordinates where the hysteresis may occur, and the ω 2 criterion theorem for computing … WebJun 20, 2024 · Pinched hysteresis loop is generally observed as a result of applying a bipolar sinusoidal voltage or current excitation signal and is thus symmetrical around the origin. Nonsymmetrical loops can also be obtained when the pinch point is …

Webeffect of a pressure of 1 MPa. The experimentally derived symmetric and pinched hysteresis loops demonstrate the capability of the device to dissipate a large amount of mechanical energy. To accurately simulate the complex force-displacement hysteresis loops characterizing the response of the tested device, we adopt the Vaiana-Rosati Model (VRM ... WebPinched hysteresis loops (PHLs) can be clockwise, counter-clockwise, self-crossing and non-self-crossing. While it is difficult to differentiate these features from the measured …
WebDec 20, 2024 · In order to hold the pinched hysteresis loop in several operating frequencies, one can observe in Eq. ( 3) that τ must be updated according to f, since k n will decrease as the frequency increases. Thus, the numeric value of τ can be updated by R 3 or C z. On the other hand, Eq. ( 3) reveals that: k n → 0 when f → ∞ or A m → 0. Hence, Eq. WebApr 8, 2024 · In particular, by varying the sign of the mismatch strain and its magnitude in a narrow range, quasi-static hysteresis-less paraelectric curves can transform into double, triple, and other types of pinched and single hysteresis loops. The strain effect on the polarization reversal is opposite, i.e., "anomalous", in comparison with many other ...
