In this lab we will study the forced Duffing oscillator, a 2 degree of freedom oscillator with cubic stiffness.
x + ax + x3 x = b cos(t)
The oscillator can exhibit chaotic (i.e. irregular) oscillations. In the applet below you need to enter the following
Click the Restart button to redraw the phase plot i.e. plot velocity against displacement.
