Weld lengthDesign codeThis study investigates ultimate behaviors such as ultimate strength and weld metal fracture mechanism of austenitic stainless steel (304 type) fillet-welded connections with TIG (tungsten inert gas) welding through experimental method. Main variables of test specimens are weld ...

- 《Fatigue & Fracture of Engineering Material & Structures》 被引量: 58发表: 2010年 Estimation of stress concentration factor at weld toe of non-load carrying fillet welded joint It has been recently shown that fatigue strength of fillet welded joints is reduced in accordance with increase of ...
In the comparison of the fatigue strength upon the post-weld treatment, the fatigue strength tends to increase according to the order: Toe Grinding, TIG Dressing, and Weld Profiling.Kab-Soo KyungSeung-Yong LeeSung-Geun LeeInternational Conference on Fracture and Damage Mechanics...
The test results showed that a Tee joint structure with an appropriate fillet weld metal toughness for the thickness of heavy gauge plates arrests a long brittle crack in the fillet weld metal. This phenomenon shows the advantage of using a fillet Tee joint for long brittle crack arrest in ...
Experimental data was also obtained and that included measurements of weld toe radius, monitoring of crack shape and S-N curves. Correlation of results with the theoretical predictions gave generally good agreement. A set of fatigue design curves for fillet welded joints is proposed and in these ...
While weld deformations vary considerably with the loading direction, weld strains are found to be independent of the loading direction. Key words: analytical model, behaviour, fillet welds, fracture angle, loading angle.doi:10.1139/l89-089Miazga, Gregory S....
The total rupture of the specimen/weld was regarded as a failure criterion of the tests. The strain gauge was placed at the distance of 0.4 t (4.8 mm) from the weld toe to verify loading conditions, considering axial and bending stress levels. Fig. 2 shows the fatigue test setup. The ...
By means of quasi-static tension applied to the branches, fracture of 12 test welds (two per connection) was obtained. Strain distributions measured adjacent to the welds indicated a weld effective length less than the total weld length, under pure axial load. Branch loads at rupture were also...
weld toeIn the study herein, the fatigue test was conducted on the fillet welds of the load carrying cruciform joint, which is frequently used in the steel structures such as bridges, ships, etc. In addition, the fatigue stress was analyzed with respect to the di...
