| Abstract: | Comparing with other formulation of the welding line,the stress theory of T-shaped joints is analyzed and then the finite element method is employed to obtain the stress distribution for two cases of tension-compression and bending.The size requirement of welding line and the effect of stress concentration are presented to meet the strength requirement for T-shaped joints.Results can be used for strength design and fatigue design of T-shaped joints in engineering. |

| Keywords: | finite element method T-shaped joint stress concentration average stress of welding line |
