An SBFEM Element for Thin-Walled Beams

International Journal of Aerospace and Lightweight Structures (IJALS), 2013
The scaled boundary finite element method (SBFEM) is a semi-analytical method in which only the boundary is discretized. The results on the boundary are scaled into the domain with respect to a scaling center which must be “visible” from the whole boundary. For beam-like problems the scaling center can be selected at infinity and only the cross-section

Hydrodynamic Pressure on Dams Based on SBFEM

Advances in Earth Structures, 2006
Dam-reservoir interaction plays an important role in the seismic response of dams. In this paper, the Scaled Boundary Finite Element Method (SBFEM) put forward by Wolf and Song is used to evaluate the dynamic water pressure acting on the dam surface during earthquakes. The basic formulas are derived.

2D fracture analysis of magnetoelectroelastic composites by the SBFEM

Composite Structures, 2015
Abstract This paper extends the scaled boundary finite element method (SBFEM) to 2D fracture analysis of magnetoelectroelastic composites. The generalized extended stress intensity factors, i.e., the stress intensity factors, the electric displacement intensity factor and the magnetic induction intensity factor, for different crack configurations and

On the use of cyclic symmetry in SBFEM for heat transfer problems

International Journal of Heat and Mass Transfer, 2014
Abstract This paper presents a SBFEM (scaled boundary finite element method) based approach for 2-D steady-state heat transfer analysis with cyclic symmetry. The global coefficient matrices of SBFEM are proved to be block-circulant in a cyclically symmetric system, and the global quadratic eigenproblem is partitioned into a series of smaller ...

Modeling the Particle Breakage by Using Combined DEM and SBFEM

2016
A novel computational method is developed in this study through the coupling of the discrete element method (DEM) and the scaled boundary finite element method (SBFEM). The objective of the developed technique is to model the particle breakage phenomenon in granular materials.

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

PAMM, 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 ...
