摘要：

A method of tube joining by plastic deformation has efficient, reliable and environmentally friendly features, so that it is widely applied into the fabrication of aviation pipeline. Internal rolling has potential to join high strength titanium alloy tubes withstanding high pressure medium with better sealing performance. Taking TA18 titanium alloy tubes as the case material, this presentation combines numerical modelling with experiments to describe the deformation behavior of joining by rolling process. The distribution of the residual contact stress and plastic strain was analyzed by partitioning the deformation regions of the tube. Finally, it is concluded that a robust and accurate FE model of Internal rolling can be obtained.
