A frequency-domain reduced order model for joints by hyper-reduction and model-driven sampling

Autor: Ahmed Amr Morsy, Mariella Kast, Paolo Tiso

Publikováno v: Mechanical Systems and Signal Processing, 185

The dynamic behavior of jointed assemblies exhibiting friction nonlinearities features amplitude-dependent dissipation and stiffness. To develop numerical simulations for predictive and design purposes, macro-scale High Fidelity Models (HFMs) of the

A non-intrusive multifidelity method for the reduced order modeling of nonlinear problems

Autor: Mengwu Guo, Mariella Kast, Jan S. Hesthaven

Publikováno v: Computer Methods in Applied Mechanics and Engineering. 364:112947

We propose a non-intrusive reduced basis (RB) method for parametrized nonlinear partial differential equations (PDEs) that leverages models of different accuracy. From a collection of low-fidelity (LF) snapshots, parameter locations are extracted for
