Abstract
The thickness and residual stress effect of fatigue performance was inverstigated on non-load-carrying fillet welded joints with thickness ranging from 12 to 38mm. As-welded and stress relieved joints were tested under both alternating and pulsating bending. Material fatigue tests on hour-glass type specimens and fatigue crack grouth tests on edge-notched specimens were also performed under fully reversed axial load and alternating and pulsating bending, respectively. In this paper, results of the tests are presented and discussed. Some aspects of fatigue performance are shown in relation to the thicknass and residual stress effect.
