抄録

Fatigue life prediction of welded joints under plane bending load and its application to fatigue behaviour analysis of welded tubular joints were performed on the basis of the results stated in the 1st Report.<BR>The results are summarized as follows.<BR>(1). The fatigue crack initiation life N_c at the weld toe could be evaluated using strain-controlled fatigue concepts.<BR>(2). The fatigue failure life N_f of welded joints under plane bending could be estimated using edge crack model with an initial crack size (a/T)_i=0.0125.<BR>(3). The fatigue life N_c and N_f in welded tubular T-and X-joints also could be evaluated from the above procedures by using hot-spot stress range Δσ_a in stead of Δσ_b.
