Heat Transfer Applications of Meshless Local Petrov-Galerkin (MLPG) Method during Plasma Spray

2007
In this work, a compact computational formulation is established based on the truly meshless method MLPG, and is firstly used to solve steady and transient heat conductions of the plasma spray. The unknown function of temperature distribution is approximated by moving least square approximation functions.

On the Application of the Meshless Local Petrov-Galerkin (MLPG) Method to the Analysis of Shear Deformable Plates

2004
The Meshless Local Petrov-Galerkin (MLPG) approach for the analysis of shear deformable plates is presented. Applying the linear test function in the plate thickness direction, the local symmetric weak form of the equilibrium equations is derived. Discretization is performed by means of the moving least squares (MLS) approximation where the nodal ...

Meshless Local Petrov Galerkin (MLPG) Method with Orthogonal Polynomials for Euler-Bernoulli Beam Problems

AIAA Scitech 2019 Forum, 2019
In this paper, the feasibility of orthogonal polynomials in the meshless local Petrov Galerkin method (MLPG) method is studied. The orthogonal polynomials, Chebyshev and Legendre polynomials, are used in this MLPG method as trial functions. The test functions used were power functions with smooth derivatives at their ends.

The Nonlinear Meshless Local Petrov-Galerkin (MLPG) Method from the Nonlinear Regular Local Boundary Integral Equation

International Journal for Computational Methods in Engineering Science and Mechanics, 2010
The meshless local Petrov-Galerkin approach based on a regular local boundary integral equation is successfully extended to solve nonlinear boundary value problems. The present method is truly meshless, as no mesh connectivity is needed for interpolating the solution variables and for integrating the weak form. Compared to the original MLPG method, the
