Meshless Local Petrov-Galerkin (MLPG) Formulation for Analysis of Thick Plates

Computer Modeling in Engineering & Sciences, 2004
An efficient meshless formulation based on the Local Petrov-Galerkin approach for the analysis of shear deformable thick plates is presented. Using the kinematics of a three-dimensional continuum, the local symmetric weak form of the equilibrium equations over the cylindrical shaped local sub-domain is derived.

Meshless Local Petrov-Galerkin (MLPG) Mixed Collocation Method For Elasticity Problems

Computer Modeling in Engineering & Sciences, 2006
The Meshless Local Petrov-Galerkin (MLPG) mixed collocation method is proposed in this paper, for solving elasticity problems. In the present MLPG approach, the mixed scheme is applied to interpolate the displacements and stresses independently, as in the MLPG finite volume method.

Meshless local Petrov-Galerkin method with complex variables for elasticity

Acta Physica Sinica, 2012
In this paper, the shape functions are obtained by the moving least-squares method with complex variable (MLSCV). The advantages of MLSCV are that the approximation function of a two-dimensional (2D) problem is formed with one-dimensional (1D) basis function, and the number of the undetermined coefficients is reduced, so it effectively improves the ...

Differential quadrature method for space-fractional diffusion equations on 2D irregular domains

, 2018
In mathematical physics, the space-fractional diffusion equations are of particular interest in the studies of physical phenomena modelled by L\'{e}vy processes, which are sometimes called super-diffusion equations.

Truly Meshless Local Petrov-Galerkin (MLPG) Solutions of Traction & Displacement BIEs

Computer Modeling in Engineering & Sciences, 2003
The numerical implementation of the truly Meshless Local Petrov-Galerkin (MLPG) type weak-forms of the displacement and traction boundary integral equations is presented, for solids undergoing small deformations. In the accompanying part I of this paper, the general MLPG/BIE weak-forms were presented [Atluri, Han and Shen (2003)].
