| Abstract: | To study the distribution of the force value, the change of the outer dimension of the expansion tube, and the residual stress distribution in the expansion tube, the three-dimensional modeling of the expansion tube and the expansion cone was established. The finite element analysis of the expansion process was carried out by ANSYS software, and the stress distribution, the expansion force value, residual stress, axial shrinkage, and the wall thickness change of the expansion pipe were obtained. It provides theoretical guidance for the construction on site. |
