Meshless Local Petrov-Galerkin (MLPG) approaches for solving 3D Problems in elasto-statics
Three different truly Meshless Local Petrov-Galerkin (MLPG) methods are developed for solving 3D elasto-static problems. Using the general MLPG concept, these methods are derived through the local weak forms of the equilibrium equations, by using ...

A Finite Element enrichment technique by the Meshless Local Petrov-Galerkin method
In the engineering practice meshing and re-meshing complex domains by Finite Elements (FE) is one of the most time-consuming efforts. Meshless methods avoid this task but are computationally more expensive than standard FE. A somewhat natural improvement

Meshless Local Petrov-Galerkin Method for Bending Problems
The Finite Element Method (FEM) is extensively used as an engineering analysis tool because of its versatility and flexibility. However, the method suffers from drawbacks such as discontinuous secondary variables across inter-element boundaries and the ...

It is shown that the MLPG method augmented with the enriched basis functions and either the visibility criterion or the diffraction criterion successfully predicts the singular stress fields near a crack tip. Results are presented for a single edge-cracked plate and a double edge-cracked plate with plate edges parallel to the crack axis loaded in ...
