| Abstract: | Based on the theory of plastic deformation and stretch reduction, using upper limit element method, an active allowed velocity field is established and some formulas are deduced which are associated with virtual work consuming of deforming body. Finally, the rolling force of stretch reduction tube was calculated and it has been verified by tests. |
