Surrogate modeling for uncertainty quantification in nonlinear dynamics
S. Marelli, S. Schär, B. Sudret
Predicting the behavior of complex systems in engineering often involves significant uncertainty about operating conditions, such as external loads, environmental effects, and manu…
mNARX+: A surrogate model for complex dynamical systems using manifold-NARX and automatic feature selection
S. Schär, S. Marelli, B. Sudret
We propose an automatic approach for manifold nonlinear autoregressive with exogenous inputs (mNARX) modeling that leverages the feature-based structure of functional-NARX (F-NARX)…
Comparison of Probabilistic Structural Reliability Methods for Ultimate Limit State Assessment of Wind Turbines
Hong Wang, Odin Gramstad, Styfen Schär +2
The probabilistic design of offshore wind turbines aims to ensure structural safety in a cost-effective way. This involves conducting structural reliability assessments for differe…
Emulating the dynamics of complex systems using autoregressive models on manifolds (mNARX)
Styfen Schär, Stefano Marelli, Bruno Sudret
We propose a novel surrogate modelling approach to efficiently and accurately approximate the response of complex dynamical systems driven by time-varying exogenous excitations ove…
