| Abstract: | Studies the internal stress and deformation of the thin-welled steel tube in the steel mould under the action of axial force, extrusion stress, internal pressure and frictional force. The elastic and plastic limit loading of the steel tube is calculated. The influence of frictional coefficient between steel tube and steel mould on the limit loading is discussed here. Finally, the calculating examples are illustrated. |
