Finite Element Analysis of the Stress Concentrations for Butt Welded Joints
Byeong-Choon Goo, Byung-Il Choi, Jai-Hoon Kim
Abstract
The purpose of this study is to investigate the intluence of weld bead profiles on stress concentration factors of double V groove butt-welded joints. The intluence of three parameters such as toe radii, tlank angles and bead heights on the stress concentration factors is studied by finite element analysis. It is shown that the three parameters have similar effects on the stress concentration factors. Finally a formula to estimate the stress concentration factors considering the three parameters and others is proposed and estimated results are compared with the results obtained by finite element analysis.
