Selective Smoothed Finite Element Method
The paper examines three selective schemes for the smoothed finite element method (SFEM) which was formulated by incorporating a cell-wise strain smoothing operation into the standard compatible finite element method (FEM). These selective SFEM schemes were formulated based on three selective integration FEM schemes with similar properties found between the number of smoothing cells in the SFEM...
متن کاملEvaluation of Fracture Parameters by Coupling the Edge-Based Smoothed Finite Element Method and the Scaled Boundary Finite Element Method
This paper presents a technique to evaluate the fracture parameters by combining the edge based smoothed finite element method (ESFEM) and the scaled boundary finite element method (SBFEM). A semi-analytical solution is sought in the region close to the vicinity of the crack tip using the SBFEM, whilst, the ESFEM is used for the rest of the domain. As both methods satisfy the partition of unity...
متن کاملSimulation of passive myocardium of rabbit ventricles, using selective smoothed finite element method(S-FEM)
A selective smoothed finite element method (Selective S-FEM) is developed for dynamic 3D analysis of extremely large deformation of incompressible bio-tissues, using the simplest 4-node tetrahedron elements. In the present selective S-FEM, face-based Smoothed FEM (FS-FEM) and node-based Smoothed FEM (NS-FEM) are, respectively, used for the deviatoric and volumetric parts of the deformation of i...
متن کاملOn the approximation in the smoothed finite element method (SFEM)
This letter aims at resolving the issues raised in the recent short communication [1] and answered by [2] by proposing a systematic approximation scheme based on non-mapped shape functions, which both allows to fully exploit the unique advantages of the smoothed finite element method and resolve the existence, linearity and posi-tivity deficiencies pointed out in [1]. We show that Wachspress in...
متن کاملHomogenization for composite material properties using smoothed finite element method
Numerical homogenization is an efficient way to determine effective material properties of composite materials. Conventionally, the finite element technique has been widely used in implementing the homogenization. However, the standard finite element method (FEM) leads to an overly-stiff model which gives poor accuracy especially using triangular elements in 2D or tetrahedral elements in 3D wit...
