Meshing Methods Effect on Double Fillet Weld Finite Element Analysis

Nancy Mary Prakash, Vaibhav Singh Rathore

Abstract


Finite element analysis of the double fillet weld joint has been conducted in the present paper. Effect of the meshing techniques has also been shown. Meshing is a very important stage which can affect the finite element results by a large amount. There are different meshing options like sizing, refinement and inflation, available; other than that, different meshing methods are also available. Meshing methods studied in the present work are; automatic, tetrahedrons and hex dominant; with that, different algorithms like, patch conforming and patch independent, have also been studied. Literature study has also been presented. Weld root and toes are the zones where maximum stress is developed, so, these zones are also called as stress concentration. Three-dimensional double fillet weld simulation has conducted. Effect of different element size has also studied. Patch conforming method suits well with tetrahedrons meshing method.

Keywords: Meshing methods, double fillet weld joint, finite element analysis

A three-dimensional double fillet weld finite element analysis has been studied.

Refinement and element size are suitable for meshing in toes and root areas, where maximum stress and distortion occur.

Patch independent is the best with tetrahedrons meshing method.

Tetrahedral and sizing meshing methods have been used for appropriate meshing of the welding root and toes.

Fine meshing increases the time of the solution.
