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.

A 2D SSM-reduced model accurately predicts the motion of the full, nonlinear, finite-element model of a plate in a random pressure field. General theory of random SSMs (random spectral submanifolds) with examples here:
