Abstract
This study investigated the fatigue stength of non-load carrying cruciform welded joints, which was maunfactured using the SM570 and POSTEN80 high strengh steel. Factors such as fatigue strength, fatigue crack initiation and propagation, thickness effect, and the relatioinship between the static strength and the fatigue strength were examined and compared with previous fatigue testing results. Results showed that the fatigue strength of SM570 and POSTEN80 steel are higher than the grade represented on the design specification. It is also identified the size effect and the dependence of the static stength in a few cases.
