Exact Model Reduction and Fast Forced Response Calculation in High-Dimensional Nonlinear Mechanical Systems

Sten Ponsioen, George Haller

We show how spectral submanifold (SSM) theory can be used to extract forced-response curves, including isolas, without any numerical simulation in high-degree-of-freedom, periodica…

Explicit Third-Order Model Reduction Formulas for General Nonlinear Mechanical Systems

Zsolt Veraszto, Sten Ponsioen, George Haller

For general nonlinear mechanical systems, we derive closed-form, reduced-order models up to cubic order based on rigorous invariant manifold results. For conservative systems, the…

Analytic Prediction of Isolated Forced Response Curves from Spectral Submanifolds

Sten Ponsioen, Tiemo Pedergnana, George Haller

We show how spectral submanifold theory can be used to provide analytic predictions for the response of periodically forced multi-degree-of-freedom mechanical systems. These predic…

Automated Computation of Autonomous Spectral Submanifolds for Nonlinear Modal Analysis

Sten Ponsioen, Tiemo Pedergnana, George Haller

We discuss an automated computational methodology for computing two-dimensional spectral submanifolds (SSMs) in autonomous nonlinear mechanical systems of arbitrary degrees of free…

Exact Model Reduction by a Slow-Fast Decomposition of Nonlinear Mechanical Systems

George Haller, Sten Ponsioen

We derive conditions under which a general nonlinear mechanical system can be exactly reduced to a lower-dimensional model that involves only the most flexible degrees of freedom.…

Nonlinear normal modes and spectral submanifolds: Existence, uniqueness and use in model reduction

George Haller, Sten Ponsioen

We propose a unified approach to nonlinear modal analysis in dissipative oscillatory systems. This approach eliminates conflicting definitions, covers both autonomous and time-depe…
