On the use of cyclic symmetry in SBFEM for heat transfer problems
International Journal of Heat and Mass Transfer, 2014Abstract 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 ...

A mixed SBFEM for stress singularities in nearly incompressible multi-materials
Computers & Structures, 2015A mixed scaled boundary finite element formulation with near incompressibility.The formulation does not require any mesh-dependent and stabilization parameters.It allows direction determination of generalized stress intensity factors.It can model strong discontinuities near crack/notch, interface crack/notch tips.Avoids volumetric locking and numerical

An SBFEM-Based Model for Hydraulic Fracturing in Quasi-Brittle Materials
Acta Mechanica Solida Sinica, 2018A numerical model based on the scaled boundary finite element method is developed to simulate the hydraulic fracturing in concrete-like quasi-brittle materials using cohesive interface elements. The shadow domain method developed previously (Yang and Deeks in Eng Fract Mech 143(4):333–354, 2007) is extended to consider crack-width-dependent hydraulic ...

Micromechanical model for polymeric nano-composites material based on SBFEM
Composite Structures, 2018Abstract In this study a novel mesh algorithm is introduced to investigate the elastic properties of Polymer Nano-composite (PNC) materials based on the scaled boundary finite element method (SBFEM). The proposed procedure is applied efficiently with very simple mesh and few degrees of freedom compared to the classical finite element method.

SBFEM elements for thin‐walled composite beams with arbitrary layup
PAMM, 2014AbstractThe 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‐

Solving viscoelastic problems by combining SBFEM and a temporally piecewise adaptive algorithm
Mechanics of Time-Dependent Materials, 2017A combination of the scaled boundary finite element method (SBFEM) with a temporally piecewise adaptive algorithm is exploited to solve viscoelastic problems. By expanding variables at a discretized time interval, a coupled spatial–temporal problem is decoupled into a series of recursive spatial problems, which are solved by SBFEM, and a piecewise ...

Numerical Simulations of Pile Integrity Tests Using a Coupled FEM SBFEM Approach
PAMM, 2012AbstractPiles are widely used to build a proper foundation for various buildings. The pile's quality in situ can be tested by a so called pile integrity test. In order to apply this test, an acceleration sensor is attached to the pile's head which than receives an impulse. Due to this impulse a p‐wave runs through the pile.
