A high-fidelity 3D S-FEM stress analysis of a highly heterogeneous swine skull

Medical & Biological Engineering & Computing, 2020
Fracture healing and growth of the bones are highly related to the stress level. Numerical analysis of stresses is the most effective means to determine the stress level, but it usually requires sufficient resolution to ensure an accurate description of geometry features of bones.

A MODIFIED TRIANGULATION ALGORITHM TAILORED FOR THE SMOOTHED FINITE ELEMENT METHOD (S-FEM)

International Journal of Computational Methods, 2013
Meshing is one of the key tasks in using the finite element method (FEM), the smoothed finite element method (S-FEM), finite volume method (FVM), and many other discrete numerical methods. Linear triangular (T3) mesh is one of the most widely used mesh, because it can be generated and refined automatically for discrete domains of complicated geometry ...

A Smoothed Finite Element Method (S-FEM) for Large-Deformation Elastoplastic Analysis

International Journal of Computational Methods, 2015
An edge-based smoothed finite element method (ES-FEM) using 3-node triangular element was recently proposed to improve the accuracy and convergence rate of the standard finite element method (FEM) for 2D elastic solid mechanics problems. In this research, ES-FEM is extended to large-deformation plasticity analysis, and a selective edge-based/node-based

Development of a Software Package of Smoothed Finite Element Method (S-FEM) for Solid Mechanics Problems

International Journal of Computational Methods, 2019
This paper reports a work to develop a general solver of smoothed finite element methods (S-FEMs) for stress analysis of 2D and 3D solid mechanics problems. In the solver, several efficient algorithms are proposed to construct the real smoothing domains and calculate all the connectivity for later computation.

3D N-S FEM Flow Analysis in Draft Tube

1993
The three dimensional flow in the draft tube of the Francis turbine for the GAMM workshop’89 was analysed with an FEM Navier-Stokes code using constant eddy viscosity. A smaller value of the eddy viscosity was used in the near wall region in comparison to that used in the core region.

Using Axisymmetric Smoothed Finite Element Method (S-FEM) to Analyze Pressure Piping with Defect in ABAQUS

International Journal of Computational Methods, 2019
Pressure piping is the most productive way for large-volume compressed natural gas (CNG) transportation. In pipeline constructions, the thickness at the point where two pipes join together is often not consistent due to the mismatch in dimensions, and thus stress concentrations can often occur at the pipe joints, causing safety concerns. Therefore, it

Study on fatigue growth of multi-surface flaws in shaft under rotary bending by S-FEM

Engineering Fracture Mechanics, 2017
Abstract In order to achieve reliable fatigue crack growth simulations of shafts under cyclic rotary bending by means of the finite element method, the Stress Intensity Factors (SIFs) along a flaw front have to be evaluated for an arbitrary rotational position. However, the evaluation of such SIFs takes much a great computation effort due to geometry
