Nonlinear Phenomena in Hysteretic Systems

Parametric identification of nonlinear hysteretic systems

The hysteretic behaviour is an essential feature of many physical systems. Such a feature is conveniently accounted for in hysteretic systems modelling through the well known nonlinear Bouc-Wen equations. But these involve several unknown parameters and internal signals that are not all accessible to measurements. These difficulties make the identification of hysteretic systems a challenging pr...

On the Dynamics of Nonlinear Hysteretic Systems

We show that the coupling of simple dynamical systems with a typical model for hysteresis, the Preisach model, leads to interesting new scenarios in nonlinear dynamics. The Preisach model is known from many branches of science to be a universal model for complex, non-local hysteresis. We provide results for three cases, for two, where the Preisach model simply acts as hysteretic transducer for ...

Nonlinear Hysteretic Torsional Waves.

We theoretically study and experimentally report the propagation of nonlinear hysteretic torsional pulses in a vertical granular chain made of cm-scale, self-hanged magnetic beads. As predicted by contact mechanics, the torsional coupling between two beads is found to be nonlinear hysteretic. This results in a nonlinear pulse distortion essentially different from the distortion predicted by cla...
