| Abstract: | In this paper, the stress and deformation of tube and tube sheet in soft medium expansion was analyzed with elasto plastic theory. And a computing procedure was proposed to determine the expanding pressure and residual contact pressure. A practical example was also used with FEM to verify the correction of the method. |
