Strength mismatch effect on yield load in X-shaped weldment with centre crack

This paper provides yield load solutions for the single edged fracture toughness specimen subjected to bending SE (B) with present X-shaped weld joint. The weld centre crack is located in the overmatch weld part. The corresponding fully plastic yield loads were obtained directly by plane strain finite element analysis for five characteristic a/W ratios: 0, 1 ; 0, 2 ; 0, 3 ; 0, 4 and 0, 5. Also, the influence of the systematically varied weld root width 2H on the fracture behaviour has been evaluated. It was found that yield load decreases with increasing of the weld root, because the undermatched region ahead the crack tip plays the dominant role.
