SBFEM for fracture analysis of piezoelectric composites under thermal load [PDF]
International Journal of Solids and Structures, 2015 Abstract This paper extends a semi-analytical technique, the so-called scaled boundary finite element method (SBFEM), to analyze fracture behaviors of piezoelectric materials and piezoelectric composites under thermal loading. In this method, only the boundary is discretized leading to a reduction of the spatial dimension by one.

An Efficient Dynamic Coupling Calculation Method for Dam–Reservoir Systems Based on FEM-SBFEM [PDF]
Water (Switzerland), 2023 In the dynamic analysis of dam–reservoir interactions, the computational efficiency of coupling system is relatively low. When numerical methods such as the scaled boundary finite element method (SBFEM) or the finite element method (FEM) are used ...

Crack analyses in porous piezoelectric brittle materials by the SBFEM
Engineering Fracture Mechanics, 2016Abstract The scaled boundary-finite element method (SBFEM) is employed to analyze cracks in porous piezoelectric solids. A large (magistral) crack and a short crack emanating from a single pore are analyzed. These cracks with their tips in the solid skeleton have the weakening effects on the fracture strength.

An SBFEM Element for Thin-Walled Beams
International Journal of Aerospace and Lightweight Structures (IJALS), 2013The 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, 2006Dam-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, 2015Abstract 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
