Improved Element-Free Galerkin method (IEFG) for solving three-dimensional elasticity problems

open access: yesInteraction and multiscale mechanics, 2010
The essential idea of the element-free Galerkin method (EFG) is that moving least-squares (MLS) approximation are used for the trial and test functions with the variational principle (weak form). By using the weighted orthogonal basis function to construct the MLS interpolants, we derive the formulae for an improved element-free Galerkin (IEFG) method ...

A review on recent contribution of meshfree methods to structure and fracture mechanics applications. [PDF]

open access: yesScientificWorldJournal, 2014
Meshfree methods are viewed as next generation computational techniques. With evident limitations of conventional grid based methods, like FEM, in dealing with problems of fracture mechanics, large deformation, and simulation of manufacturing processes, meshfree methods have gained much attention by researchers.

A Hybrid Interpolating Meshless Method for 3D Advection–Diffusion Problems

open access: yesMathematics, 2022
A hybrid interpolating meshless (HIM) method is established for dealing with three-dimensional (3D) advection–diffusion equations. To improve computational efficiency, a 3D equation is changed into correlative two-dimensional (2D) equations. The improved
