Effect of Technological Parameters on the Profile Extrusion Process
The non-homogeneous metal flow during the extrusion process is well controlled by introducing a reflecting non-equilibrium parameter of metal flow —— the mean-square deviation of velocity ( SDV ) in this paper. The finite deformation elastoplastic finite element method is used to carry out the numerical simulation research on the profile extrusion process with the different extrusion parameters (such as extrusion ratio, frictional factor). The varied laws of the extrusion pressure, SDV and stress-strain fields with the extrusion parameters are obtained. It is a theoretic consideration to optimize the technological parameters in the profile extrusion process.
