C. Thaulow et al., FE CALCULATIONS OF STRESS-FIELDS FROM CRACKS LOCATED AT THE FUSION LINE OF WELDMENTS, Engineering fracture mechanics, 57(6), 1997, pp. 637-651
This paper investigates the stress fields for a crack located at the f
usion line of a weldment. The strength mis-matching and the size of th
e HAZ were varied, and the corresponding distribution of the maximum p
rincipal stress was examined. The weld metal strength was globally ove
rmatched with respect to the base material, but locally over-and under
matched with respect to the heat affected zone. Three cases of mis-mat
ch were compared, and it was found that reducing the strength of the H
AZ lowered the maximum principal stresses. (C) 1997 Elsevier Science L
