An s-version finite element method without generation of coupling stiffness matrix by using iterative technique

Mechanical Engineering Journal, 2016
In s-version finite element method (s-FEM) proposed by Fish (1992), a local mesh that represents the local feature such as a hole or a crack is superposed on a global mesh that represents the shape of the whole analysis model.

Fatigue crack growth simulation of two non-coplanar embedded cracks using s-version finite element method

Fracture and Structural Integrity, 2019
In this paper, the fatigue crack growth simulation of two non-coplanar embedded cracks using the s-version finite element method is presented, and the validity and reliability of the alignment rule for two non-coplanar cracks are evaluated.

Predicting Fatigue Crack Growth Behavior of Coalesced Cracks Using the Global-Local Superimposed Technique

Fracture and Structural Integrity, 2022
The S-version Finite Element Method (FEM) is known as a global-local superimposed approach that consists of two separate meshes referred to as global and local cracks. The relationship between the energy release rate and the Stress Intensity Factor (SIF)

Parallel parametric analysis approach based on an s-version FEM for fracture mechanics analysis in designing hole positions

Mechanical Engineering Journal, 2023
This study proposes a parallel parametric analysis approach, in which parametric analysis for a local shape, such as a hole, is automated and parallelized. For the automation, the present approach is based on an s-version FEM, namely, the coupling-matrix-

The finite-volume method in computational rheology [PDF]

, 2012
The finite volume method (FVM) is widely used in traditional computational fluid dynamics (CFD), and many commercial CFD codes are based on this technique which is typically less demanding in computational resources than finite element methods (FEM ...

On the Linear Dependencies of Interpolation Functions in s-Version Finite Element Method

Journal of Computational Science and Technology, 2009
In this paper, we first point out that the finite element interpolation functions sometime lose their linear independencies when the elements are superposed each other in s-Version finite element (s-FEM) analyses. This problem has been known among engineers/researchers who have studied and used the s-FEM for solid mechanics analyses.

Analysis of a many-hole problem using coupling-matrix-free iterative s-version FEM with multiple local meshes

Mechanical Engineering Journal, 2018
The coupling-matrix-free iterative s-version finite element method is extended to multiple local meshes in order to model multiple local features such as holes, inclusions, and cracks.
