Analysis of constraint effect on fracture behaviour of mis-match welded joint

The differences in mechanical properties amongst different welded joints' regions obviously affect the strain distribution around the crack tip during the fracture test and, hence, influence the toughness value. The strength mis-match and width of welded joint have an effect on the stress-strain distribution in the vicinity of the crack tip. Both can contribute to a higher constraint in the weld metal. It was found in a combined experimental and numerical study that the width of the welded joint as a constraint parameter has an effect on the limit load, maximum load and achieved fracture toughness values of a welded joint. In the case of strength overmatched welded joints, the limit and maximum loads increase with decreasing constraint, i.e. with increasing weld width. On th contrary, in the case of strength undermatched welded joints the limit and maximum loads and the constraint decrease with the width of the welded joint width.
