Robust modelling of implicit interfaces by the scaled boundary finite element method [PDF]

open access: yes, 2021
In this paper, we propose a robust framework based on the scaled boundary finite element method to model implicit interfaces in two-dimensional differential equations in nonhomegeneous media.

Scaled boundary finite element method for fluid-structure interaction [PDF]

open access: yes, 2006
This study presents the first attempt to extend the scaled boundary finite element method (SBFEM) for Fluid-Structure-Interaction problems. A fluid velocity-to-pressure relationship based on the SBFEM and acoustic approximations is developed. A FEM/SBFEM

A Nonlinear Crack Model for Concrete Structure Based on an Extended Scaled Boundary Finite Element Method

open access: yesApplied Sciences, 2018
Fracture mechanics is one of the most important approaches to structural safety analysis. Modeling the fracture process zone (FPZ) is critical to understand the nonlinear cracking behavior of heterogeneous quasi-brittle materials such as concrete.

An adaptive scaled boundary finite element method for contact analysis [PDF]

open access: yes, 2021
In this work, we propose a framework for an adaptive contact analysis in deformable solids using the effective error indicator from the scaled boundary finite element method (SBFEM) with a quadtree decomposition.

On the influence of far-field model reduction techniques using a coupled FEM-SBFEM approach in time domain

open access: yesJournal of Mathematical Sciences and Modelling, 2018
To analyse soil-structure-interaction problems, often unbounded domain has to be taken into account. Since the finite element method (FEM) does not provide open boundary itself the scaled boundary finite element method (SBFEM) which fulfils the radiation

Scaled boundary finite element method for compressible and nearly incompressible elasticity over arbitrary polytopes [PDF]

open access: yes, 2019
In this paper, a purely displacement-based formulation is presented within the framework of the scaled boundary finite element method to model compressible and nearly incompressible materials.

Yarn level finite element method simulation for bending over sheaves of braided ropes

open access: yesJournal of Industrial Textiles, 2023
The complex problem of ropes (cyclic) bending over sheaves (CBOS) is considered in this article. Ropes that are used to manoeuvre and regulate sails undergo a variety of dynamic stresses which are crucial yet difficult to determine, due to the complexity
