Nonlinear Moment Matching for the Simulation-Free Reduction of Structural Systems
Maria Cruz Varona, Nico Schneucker, Boris Lohmann
This paper transfers the concept of moment matching to nonlinear structural systems and further provides a simulation-free reduction scheme for such nonlinear second-order models.…
Practicable Simulation-Free Model Order Reduction by Nonlinear Moment Matching
Maria Cruz Varona, Raphael Gebhart, Julian Suk +1
In this paper, a practicable simulation-free model order reduction method by nonlinear moment matching is developed. Based on the steady-state interpretation of linear moment match…
Impulse response of bilinear systems based on Volterra series representation
Maria Cruz Varona, Raphael Gebhart
This paper focuses on the systems theory of bilinear dynamical systems using the Volterra series representation. The main contributions are threefold. First, we gain an input-outpu…
Parametric model order reduction and its application to inverse analysis of large nonlinear coupled cardiac problems
Martin R. Pfaller, Maria Cruz Varona, Johannes Lang +2
Predictive high-fidelity finite element simulations of human cardiac mechanics co\-mmon\-ly require a large number of structural degrees of freedom. Additionally, these models are…
Model reduction of linear time-varying systems with applications for moving loads
Maria Cruz Varona, Boris Lohmann
In this paper we consider different model reduction techniques for systems with moving loads. Due to the time-dependency of the input and output matrices, the application of time-v…
