In this paper, the fatigue limits of simulated butt-welded joints were obtained under reversed bending and the results were discussed based on the critical condition for existence of a non-propagating crack.
It is well known that there is a close connection between the fatigue strength and the flank angle of a welded joint, as point out by Newman and Gurney. However, the relation shows a considerable amount of scatter.
According to the present results, the cause of the scatter can be explained through the critical condition above mentioned.
