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.

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 ...

A Coupled SBFEM-FEM Approach for Evaluating Stress Intensity Factors
Applied Mechanics and Materials, 2013A coupled method between the Scaled Boundary Finite Element Method (SBFEM) and Finite Element Method (FEM) for evaluating the Stress Intensity Factors (SIFs) is presented and achieved on the platform of the commercial finite element software ABAQUS by using Python as the programming language.

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‐

Evaluation of the Higher Order Terms of the Wedge-Splitting Specimen Based on the SBFEM
Applied Mechanics and Materials, 2013The scaled boundary finite element method (abbr. SBFEM) is a semi-analytical method developed by Wolf and Song. The analytical advantage of the solution in the radial direction allows SBFEM converge to the Williams expansion. The coefficients of the Williams expansion, including the stress intensity factor, the T-stress, and higher order terms can be ...

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 ...

LARGE SCALE SIMULATION OF WAVE PROPAGATION IN SOILS INTERACTING WITH STRUCTURES USING FEM AND SBFEM
Journal of Computational Acoustics, 2011This 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.

Transient Analysis of Dam-Reservoir Interaction Based on Dynamic Stiffness of SBFEM
Advanced Materials Research, 2011The 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
