A Phantom-Node Method with Edge-Based Strain Smoothing for Linear Elastic Fracture Mechanics [PDF]

open access: yesJournal of Applied Mathematics, 2013
This paper presents a novel numerical procedure based on the combination of an edge-based smoothed finite element (ES-FEM) with a phantom-node method for 2D linear elastic fracture mechanics. In the standard phantom-node method, the cracks are formulated

The strong formulation finite element method: stability and accuracy [PDF]

open access: yesFracture and Structural Integrity, 2014
The Strong Formulation Finite Element Method (SFEM) is a numerical solution technique for solving arbitrarily shaped structural systems. This method uses a hybrid scheme given by the Differential Quadrature Method (DQM) and the Finite Element Method (FEM)

A FEM-Green Approach for Magnetic Field Problems with Open Boundaries

open access: yesMathematics, 2021
A new finite element method/boundary element method (FEM/BEM) scheme is proposed for the solution of the 2D magnetic static and quasi-static problems with unbounded domains. The novelty is an original approach in the treatment of the outer region.

Adaptive mesh refinements for analyses of 2D linear elasticity problems using the Kriging-based finite element method [PDF]

open access: yesE3S Web of Conferences, 2023
Finite element analyses of irregular structures require adaptive mesh refinement to achieve more accurate results in an efficient manner. This is also true for a non-conventional finite element method with Kriging interpolation, called the Kriging-based ...

$\phi$-FEM: A Finite Element Method on Domains Defined by Level-Sets [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2020
We propose a new fictitious domain finite element method, well suited for elliptic problems posed in a domain given by a level-set function without requiring a mesh fitting the boundary. To impose the Dirichlet boundary conditions, we search the approximation to the solution as a product of a finite element function with the given level-set function ...
