... This paper predicts the cleavage resistance of steel welds in the ductile-to-brittle transition region by the Local Approach. Attention is payed to the strength mismatch effect on the ductile tearing and subsequent cleavage fracture. Welded joints of pipeline steels, X65 and X80 steels according...

... capsules producing larger amount of He. Although the He/dpa ratio affected the microstructural change, the impact on the post irradiation tensile behavior was rather small not only for base metal specimens but also for the weld joint and the weld metal specimens. Austenitic stainless steel...

... Fracture mechanics test results for welded joints are affected by the mechanical and metallurgical inhomogeneity in welds. The size of embrittled region encountered by the notch tip and the strength mismatch between the base and weld metals are major factors controlling the fracture resistance...

... This paper shows that, in the temperature transition regime, scatter of weld metal and heat-affected zone toughness values is related to material heterogeneity in the welded joints. Results were obtained from impact testing of V-notched and fatigue-cracked Charpy specimens as well as from static...

... The stress-intensity factor for a semi-elliptical surface crack in T-butt welded joints has been studied by using the weight function approach. The weight functions for cracks in welded joints have been derived by employing the method proposed by Petroski-Achenbach. The calculated stress...
