Abstract

Abstract

The complete velocity model for plastic metal is structured with flow function.The boundary tear stress condition, which should be met by the velocity field of the Mises material plan or axisymmetrical deformation, is raised. The stress field corresponding the velocity could be obtained by the resolution of one point uniform stress and the answer for tube drawing process is ascertained with this sort of theorem.
