説明

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. In this paper, distribution of the residual stresses near the welds measured by both a X-ray technique and a strain-gauge method is presented and discussed. The effect of residual stresses and plate thickness on fatigue strength at 2×10^6 cycles are discussed by using the present and past test results
