Scaled Boundary Finite Element Method for Mid-Frequency Acoustics of Cavities
Journal of Theoretical and Computational Acoustics, 2021In this paper, a semi-analytical framework, based on the scaled boundary finite element method (SBFEM), is proposed, to study interior acoustic problems in the mid-frequency range in two and three dimensions. The SBFEM shares the advantages of both the finite element method (FEM) and the boundary element method (BEM). Like the FEM, it does not require

An adaptive polytree approach to the scaled boundary boundary finite element method
International Journal of Advances in Engineering Sciences and Applied Mathematics, 2020In this paper, a h-adaptive methodology based on the polytopal meshes is proposed for capturing high stress gradients at the materials corners and the stress singularities at the vicinity of a crack tip. The adaptive refinement is based on the error indicator directly computed from the displacement solutions of the scaled boundary finite element method.

Computers & Structures, 2008
This paper introduces an algorithm for coupling the boundary element method and the scaled boundary finite element method. Although the particular application concerns the determination of stress intensity factors at crack tips, the approach is general in nature. The motivation for the work is the combination of the semi-analytical solution accuracy of

Response of unbounded soil in scaled boundary finite‐element method
Earthquake Engineering & Structural Dynamics, 2001AbstractThe scaled boundary finite‐element method is a powerful semi‐analytical computational procedure to calculate the dynamic stiffness of the unbounded soil at the structure–soil interface. This permits the analysis of dynamic soil–structure interaction using the substructure method.

The Scaled Boundary Finite-Element Method: State of the Art
1998This paper presents the state of the art of the scaled boundary finite-element method using elastodynamics as an example. In this boundary-element method based on finite elements only the boundary is discretized with surface finite elements yielding a reduction of the spatial dimension by one.

The Scaled Boundary Finite-Element Method: Future Developments
1998In the accompanying paper “The scaled boundary finite-element method: state of the art”, published in the same proceedings [Wolf and Song, 1998], the present state of the method for elastodynamics is summarized. After discretizing the boundary with finite elements and applying the scaled boundary transformation (Fig. 1) and Galerkin’s weighted residual

Analysis of Concentrated Boundary Loads in the Scaled Boundary Finite Element Method
2006The scaled boundary finite element method models linear elastostatics problems excellently and out-performs the finite element method (FEM) when solving problems involving unbounded domains or stress singularities. This paper introduces a technique for solving concentrated boundary load problems using the scaled boundary finite element method.
