Duffing oscillator
Duffing oscillator is an example of a periodically forced oscillator with a nonlinear elasticity, written as
(1)
\ddot x + \delta \dot x + \beta x + \alpha x^3 = \gamma \cos \omega t ,
where the damping constant obeys \delta\geq 0, and it is also known as a simple model which yields chaos, as well as van der Pol oscillator.
