The dynamics of a nonlinearly coupled electro-magneto-mechanical system is numerically investigated with the aim to obtain a comprehensive description of its behavior in strongly nonlinear regime. Bifurcation diagrams and stability charts as a function of the main system parameters allow to detect several multistable and unstable regions, characterized by coexistence of low-amplitude and high-amplitude responses, and by the presence of wide ranges of chaotic motions, which have been connoted by computing the relevant Lyapunov characteristic exponents.

Abstract

The dynamics of a nonlinearly coupled electro-magneto-mechanical system is numerically investigated with the aim to obtain a comprehensive description of its behavior in strongly nonlinear regime. Bifurcation diagrams and stability charts as a function of the main system parameters allow to detect several multistable and unstable regions, characterized by coexistence of low-amplitude and high-amplitude responses, and by the presence of wide ranges of chaotic motions, which have been connoted by computing the relevant Lyapunov characteristic exponents.
