Study of some rheological models with a finite number of degrees of freedom. (English) Zbl 0954.74011
Summary: We show that a large number of rheological models can be covered by the existence and uniqueness theory for maximal monotone operators. Numerical simulations display hysteresis cycles when the forcing is periodic. We demonstrate that a given shape of hysteresis cycle in an appropriate class of polygonal cycles can be always realized by adjusting the physical parameters of rheological model.
