Numerical Simulation for Dynamic Crack Propagation by MLPG
Key Engineering Materials, 2006In this paper, a new algorithm based on Meshless Local Petrov-Galerking (MLPG) method is presented for analyzing the crack dynamic propagation. A new modified Moving Least Squares approximation is proposed to simplify the treatment of essential boundary conditions.

MLPG method for convection-dominated flow problems
Progress in Computational Fluid Dynamics, An International Journal, 2012In this paper, the Meshless Local Petrov-Galerkin (MLPG) method is applied to compute convection-dominated flow problems. The results of the MLPG method are compared with the results of the finite volume method. The results show that the first-order upwind (FUD) scheme exhibits the false diffusion at a larger-Peclet number; the QUICK scheme and the ...

The MLPG for crack analyses in composites with flexoelectricity effects
Composite Structures, 2018Abstract The meshless Petrov-Galerkin (MLPG) method is developed to analyse 2-D crack problems where the electric field and displacement gradients exhibit a size effect. The size-effect phenomenon in micro/nano electronic structures is described by the strain- and electric field-gradients.

Meshless local Petrov‐Galerkin (MLPG) methods in quantum mechanics
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2011PurposeThe purpose of this paper is to solve both eigenvalue and boundary value problems coming from the field of quantum mechanics through the application of meshless methods, particularly the one known as meshless local Petrov‐Galerkin (MLPG).Design/methodology/approachRegarding eigenvalue problems, the authors show how to apply MLPG to the time ...

Analysis of an MLPG Solution for 3D Potential Problems
2008Meshless methods have been explored in many 2D problems and they have been shown to be as accurate as Finite ElementMethods (FEM). Compared to the vast literature on 2D applications, papers on solving 3D problems by meshless methods are surprisingly few. Indeed, a main drawback of these methods is the requirement for accurate cubature rules. This paper

Efficient cubature formulae for MLPG and related methods
International Journal for Numerical Methods in Engineering, 2005AbstractThe paper introduces four kinds of compact, simple to implement Gaussian cubature formulae for approximating the domain integrals arising in the discrete local weak form (DLWF) of a governing partial differential equation solved by means of the meshless local Petrov–Galerkin method of type MLPG1.

On an efficient MLPG formulation for shell analysis
2010A meshless formulation based on the local Petrov- Galerkin approach is developed for analysis of shell structures. A 3-D solid concept usually used in the finite element formulations is adopted, and the exact shell geometry may be described. The shell continuum is discretized in the parametric space defined in the normalized coordinates by the nodes ...
