Meshless local Petrov-Galerkin (MLPG) method in combination with finite element and boundary element approaches [PDF]
Computational Mechanics, 2000 Combinations of the meshless local Petrov-Galerkin (MLPG) method with finite element (FE) and boundary element (BE) methods are proposed for elasticity boundary value problems with the aim to improve the solution efficiency. Special interface elements are needed along the border of MLPG and FE (or BE) regions in order to satisfy the displacement ...

Meshless Local Petrov-Galerkin (MLPG) Method for Convection-Diffusion Problems
Computer Modeling in Engineering & Sciences, 2000 Due to the very general nature of the Meshless Local Petrov-Galerkin (MLPG) method, it is very easy and natural to introduce the upwinding concept (even in multi-dimensional cases) in the MLPG method, in order to deal with convection-dominated flows. In this paper, several upwinding schemes are proposed, and applied to solve steady convection-diffusion

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 (MLPG) Mixed Finite Difference Method for Solid Mechanics
Computer Modeling in Engineering & Sciences, 2006 The Finite Difference Method (FDM), within the framework of the Meshless Local Petrov-Galerkin (MLPG) approach, is proposed in this paper for solving solid mechanics problems. A "mixed'' interpolation scheme is adopted in the present implementation: the displacements, displacement gradients, and stresses are interpolated independently using identical ...

The Meshless Local Petrov-Galerkin (MLPG) Method for Solving Incompressible Navier-Stokes Equations
Computer Modeling in Engineering & Sciences, 2001 The truly Meshless Local Petrov-Galerkin (MLPG) method is extended to solve the incompressible Navier-Stokes equations. The local weak form is modified in a very careful way so as to ovecome the so-called Babus~ka-Brezzi conditions. In addition, The upwinding scheme as developed in Lin and Atluri (2000a) and Lin and Atluri (2000b) is used to stabilize ...

Meshless Local Petrov-Galerkin (MLPG) Method for Shear Deformable Shells Analysis
Computer Modeling in Engineering & Sciences, 2006 A meshless local Petrov-Galerkin (MLPG) method is applied to solve bending problems of shear deformable shallow shells described by the Reissner theory. Both static and dynamic loads are considered. For transient elastodynamic case the Laplace-transform is used to eliminate the time dependence of the field variables.

Multiscale Simulation Based on The Meshless Local Petrov-Galerkin (MLPG) Method
Computer Modeling in Engineering & Sciences, 2004 A multiscale simulation technique based on the MLPG methods, and finite deformation mechanics, is developed, implemented, and tested. Several alternate time-dependent interfacial conditions, between the atomistic and continuum regions, are systematically studied, for the seamless multiscale simulation, by decomposing the displacement of atoms in the ...
