Fatigue Strength of Fillet Welded Joint subjected to Plate Bending

다국어 초록 (Multilingual Abstract)

Fatigue tests have been carried out on three types of non load-carrying fillet welded joint subjected plate bending, such as single-side fillet welded joint, T-shaped fillet welded joint and cruciform fillet welded joint. Fatigue failure of each welded joint has been demonstrated. The test results show that fatigue crack forms flat semi-ellipse during crack propagation and propagates to about 80% of plate thickness before failure. The fatigue strength and life recorded under bending test have been examined and compared with the previous results obtained by tension test. The fatigue strength of the fillet welded joint under bending
is higher than that of the welded joint under tension.
