Since the deformation of the sample in this case is not a simple stress states forging, but should be seen as a complex structure of. So the question we face is that the test results of the constitutive parameters of how the anti-calculated from a complex material structural deformation. On the trunk of the material it has been established there is an inverse can not be forged, but for physical OAU lines and geometric nonlinearity strong temperature forging process, this approach will not do anything. Processing and calculation methods and general configuration of the analysis on the contact boundary compared to simulate forging process is characterized by the contact borders of the workpiece and the die is time varying. This processing and calculations related to the contact boundary friction mechanism, several aspects of contact with the judge out of the search methods and criteria, method to calculate the contact force methods.
