Analysis of Defective Tubular Welded Joints

[摘要] Oilfield exploration and production facilities are frequently required to operate in hostile environments, thus significantly increasing both the chances of, and damage caused by, failure of a structure. Many offshore oil installations consist of tubular sections connected by structural welds. Stress concentrations due to the joint geometry increase the possibility of fatigue cracking and it is common to find that the life of a joint is reduced by the presence of cracks. It is incumbent on the operator to carry out a repair on identified and significant cracks. The FE analysis of defective tubular joints is frequently used as a guide to the general behaviour of such joints rather than for specific analyses of real life faults.
