Excited to announce our paper, "A piezoelectric nonlinear energy sink shunt for vibration damping," in collaboration between @ugent and @ENSAM! 🌟 Published in Mechanical Systems and Signal Processing. (1/2)
The power of data-driven spectral submanifold (SSM) reduction: Nonlinear oscillations of an elastic flag in counter flow, together with its reconstructed chaotic attractor within a 4D SSM. Obtained directly from the videos of the experiment.

Nonlinear model reduction to spectral submanifolds is now available even under general (e.g., chaotic) forcing. Asymptotic expansions for generalized
steady states of aperiodically forced mechanical systems also follow from these results.

@Arnaldo_AGITF This looks like what would happen if a mass is dropped on a spring. (This is the typical high-school problem, which only considered this in a static way)
@stevenstrogatz@YouTube Hello Steven, big fan since I read your nonlinear dynamics book in 2014! What hardware and software did you use to make this movie clip?
