Abstract：

For the structure integrity of thread joint after forming, which is a difficult technique in mono-diameter expandable tubular, the influence of expansion cone angle on the formability of thread joint in the expansion process was studied. The steel TWIP was selected as material of expandable tubular, and the expansion process of expandable tubular thread joint under the expansion ratio of 20% was simulated by using finite element software ABAQUS. Furthermore, the influences of expansion cone angle on the required expansion force, the residual stress and the clearance between thread teeth were analyzed. The results show that the required expansion force is the smallest with the cone angle of 10°, and the distribution of residual stress inside thread joint is basically same under different cone angles. However, there are stress concentrations at contact position between thread root and thread teeth, and the residual stress in the thread joint is in better condition with cone angles of 7° and 9°, and the clearance between thread teeth is lower under cone angles of 7° and 8°.
