SBFEM with reduced modal basis for hydrodynamic bearings [PDF]

open access: hybridPAMM, 2023
AbstractThe numerical effort of transient rotordynamic simulations is often dominated by the computation of nonlinear hydrodynamic bearing forces. These forces are described by the Reynolds equation and need to be computed at every time step. Usually, numerical models, analytical approximations, or look‐up table techniques are employed, depending on ...

SBFEM with perturbation method for solving the Reynolds equation [PDF]

open access: hybridPAMM
AbstractRotordynamic simulations with nonlinear hydrodynamic bearing forces require a solution of the Reynolds equation at every time step. As a computationally efficient alternative to the standard numerical methods, a semi‐analytical solution based on the scaled boundary finite element method (SBFEM) was developed recently.

Elasto-plastic analysis with a coupled FEM/SBFEM approach [PDF]

open access: yes, 2011
In der vorliegenden Arbeit wird eine neue Methode vorgestellt, mit der sich elastisch-plastische Baugrundverformungen und elastisch-plastisch berechnetes Baugrundversagen unter Einbezug der Wellenausbreitung im Baugrund berechnen lassen. Die vorgestellte Methode ist eine hybride Methode basierend auf mehreren Berechnungsmethoden.

Transient Analysis of Dam-Reservoir Interaction Based on Dynamic Stiffness of SBFEM [PDF]

open access: yesAdvanced Materials Research, 2011
The scaled boundary finite element method (SBFEM) was extended to solve dam-reservoir interaction problems in the time domain and a dynamic stiffness used in the SBFEM of semi-infinite reservoir in the time domain was proposed, which was evaluated by the Bessel function. Based on the dynamic stiffness, transient responses subjected to horizontal ground

LARGE SCALE SIMULATION OF WAVE PROPAGATION IN SOILS INTERACTING WITH STRUCTURES USING FEM AND SBFEM [PDF]

open access: greenJournal of Computational Acoustics, 2011
This paper applies a parallel algorithm for a coupled Finite Element/Scaled Boundary Element (FEM/SBFEM)-approach to study soil-structure-interaction problems. The application code is designed to run on clusters of computers, and it enables the analysis of large-scale problems.

Three-dimensional image-based modeling by combining SBFEM and transfinite element shape functions [PDF]

open access: hybrid, 2020
The scaled boundary finite element method (SBFEM) has recently been employed as an efficient means to model three-dimensional structures, in particular when the geometry is provided as a voxel-based image.

Automatic quadtree‐based modeling using a coupled SBFEM/SCM approach [PDF]

open access: bronzePAMM, 2017
AbstractWe present an approach for the automatic image‐based modeling in computational mechanics. The geometry is divided into subdomains by employing a quadtree‐decomposition. The scaled boundary finite element method (SBFEM) can directly be applied to quadtree meshes without introducing hanging nodes, while the spectral cell method (SCM) allows for ...
