Forced Coupled Duffing Oscillators with Nonlinear Damping: Resonance and Antiresonance

Abstract

In this work, we investigate resonance and antiresonance behaviour in forced coupled Duffing oscillators with nonlinear damping. Further, we will analyse the parameter dependence of the frequency response and stability. In the course of all the analysis, emphasis shall be on how different damping mechanisms contrast against each other.
