In this article, based on the operational matrix of fractional order integration, we introduce a
method for the numerical solution of fractional strongly nonlinear Duffing oscillators with …

This work introduces an analytical technique for determining solutions to a highly nonlinear
Duffing-harmonic oscillator model problem. The parametric solutions of Duffing oscillator …

In this paper, chaotic dynamics of a cubic-quintic-septic Duffing oscillator subjected to
periodic excitation is investigated. The multiple scales method is used to determine the …

The study of nonlinear dynamical systems subjected to external periodic forces led to
several fascinating phenomena. Such extremely interesting phenomena include resonance …
