An improved interpolating element-free Galerkin method for elasticity [PDF]

open access: yesChinese Physics B, 2013
Based on the improved interpolating moving least-squares (IIMLS) method and the Galerkin weak form, an improved interpolating element-free Galerkin (IIEFG) method is presented for two-dimensional elasticity problems in this paper. Compared with the interpolating moving least-squares (IMLS) method presented by Lancaster, the IIMLS method uses the ...

A two-level enriched finite element method for a mixed problem [PDF]

open access: yes, 2011
The simplest pair of spaces is made inf-sup stable for the mixed form of the Darcy equation. The key ingredient is to enhance the finite element spaces inside a Petrov-Galerkin framework with functions satisfying element-wise local Darcy problems with ...

Improved complex variable element-free Galerkin method for viscoelasticity problems [PDF]

open access: yesActa Physica Sinica, 2014
In this paper, based on the improved complex variable least-square (ICVMLS) approximation, the improved complex variable element-free Galerkin (ICVEFG) method for two-dimensional viscoelasticity problems is proposed. The ICVMLS approximation is used to form the shape function, the Galerkin weak form is used to obtain the system equations, and the ...

A discontinuous Galerkin moving mesh method for Hamilton-Jacobi equations [PDF]

open access: yes, 2007
In this paper we consider the numerical solution of first-order Hamilton-Jacobi equations using the combination of a discontinuous Galerkin finite element method and an adaptive $r$-refinement (mesh movement) strategy.

An hp-version discontinuous Galerkin method for integro-differential equations of parabolic type [PDF]

open access: yes, 2011
We study the numerical solution of a class of parabolic integro-differential equations with weakly singular kernels. We use an $hp$-version discontinuous Galerkin (DG) method for the discretization in time.

The improved element-free Galerkin method for elastoplasticity large deformation problems [PDF]

open access: yesSCIENTIA SINICA Physica, Mechanica & Astronomica, 2018
Based on the improved moving least-squares (IMLS) approximation, the improved element-free Galerkin (IEFG) method for elastoplasticity large deformation problems is presented. Compared with the moving least-squares (MLS) approximation, by orthogonalizing the basis function, the IMLS approximation can overcome the disadvantage of ill-conditional or ...

Numerical solution for one-dimensional pure-convection problems using the high-order Taylor-Galerkin element-free method [PDF]

open access: yesمهندسی عمران شریف
The present study proposes a novel approach for solving one-dimensional pure convection problems, utilizing a high-order Taylor Galerkin element-free method. The standard Galerkin method has limitations in solving such problems due to the predominance of
