Abstract
In the present work, hysteresis is simulated by means of internal
variables. Analytical models of different types of hysteresis
loops enable reproduction of major and minor loops and provide
good agreement with experimental data. Using an effective
algorithm based on the analysis of wandering trajectories, an
evolution of chaotic behavior regions of oscillators with
hysteresis is presented in various parametric planes. A
substantial influence of a hysteretic dissipation value on the
form and location of these regions and also restraining and
generating effects of the hysteretic dissipation on chaos
occurrence are shown. It was demonstrated that for fixed
parameters, which govern the shape of a hysteresis loop, the
extent of pinch of this loop could be controlled by means of the
amplitude and frequency of external periodic excitation.
