  author={Chaemin Lee and Jongho Park},
Strain smoothing methods such as the smoothed finite element methods (S-FEMs) and the strain-smoothed element (SSE) method have successfully improved the performance of finite elements, and there have been numerous applications of them in finite element analysis. For the sake of efficient applications to large-scale problems, it is important to develop a mathematically and numerically well-elaborated iterative solver for the strain smoothing methods. In this paper, inspired by the spectral… 


A theoretical study on the smoothed FEM (S‐FEM) models: Properties, accuracy and convergence rates
Incorporating the strain smoothing technique of meshfree methods into the standard finite element method (FEM), Liu et al. have recently proposed a series of smoothed finite element methods (S-FEM)
A variational framework for the strain-smoothed element method
A mixed variational principle is proposed in which the SSE method can be interpreted as a Galerkin approximation of that, and various existing methods such as smoothed finite element methods can be expressed in terms of the proposed Variational principle.
On Smoothed Finite Element Methods
The paper presents an overview of the smoothed finite element methods (S-FEM) which are formulated by combining the existing standard FEM with the strain smoothing techniques used in the meshfree
Smooth finite element methods: Convergence, accuracy and properties
A stabilized conforming nodal integration finite element method based on strain smoothing stabilization is presented. The integration of the stiffness matrix is performed on the boundaries of the
Smoothed Finite Element Methods (S-FEM): An Overview and Recent Developments
The smoothed finite element methods (S-FEM) are a family of methods formulated through carefully designed combinations of the standard FEM and some of the techniques from the meshfree methods.
A Smoothed Finite Element Method for Mechanics Problems
In the finite element method (FEM), a necessary condition for a four-node isoparametric element is that no interior angle is greater than 180° and the positivity of Jacobian determinant should be
An edge-based smoothed finite element method (ES-FEM) for static, free and forced vibration analyses of solids
Abstract This paper presents an edge-based smoothed finite element method (ES-FEM) to significantly improve the accuracy of the finite element method (FEM) without much changing to the standard FEM
A stabilized conforming nodal integration for Galerkin mesh-free methods
Domain integration by Gauss quadrature in the Galerkin mesh-free methods adds considerable complexity to solution procedures. Direct nodal integration, on the other hand, leads to a numerical
An Optimal Domain Decomposition Preconditioner for the Finite Element Solution of Linear Elasticity Problems
It is proven that the condition number of the resulting system does not grow as the substructures are made smaller and the mesh is refined, and this result holds for two and three dimensions.
The strain-smoothed 4-node quadrilateral finite element
Abstract Recently, the strain-smoothed element (SSE) method has been developed for 3-node triangular and 4-node tetrahedral solid elements. The method was also applied for enhancing the membrane
