... and a Duffing Oscillator; the other degree of freedom is a mass on a spring and a damper, in this case a cylinder. Thus, this model can be considered one of fluid-structure interaction. The cubic stiffening from the Duffing Oscillator proved to improve the match to experimental data. Using this model to study...
