Elastic-plastic model to calculate the precise forging Which is good, but to determine the yield and unloading due to increased amount of computation. Rigid-plastic model is relatively simple, but can not simulate springback calculation process. In these models typically only consider the strain hardening. Considered the most dynamic recovery forging sales, and therefore able to meet the requirements of conventional cold and warm forging process simulation. But for those who have accompanied the process of forming the microstructure changes in circumstances (such as forging, superplastic forming) the use of the traditional constitutive relationship will produce a lot of errors. After about testing methods material constitutive parameters of constitutive equations with the right, the question is how to further test these include material parameters measured in the constitutive equations. For conventional elastic-plastic / rigid plastic constitutive model forging, usually simple stress tests (tension, compression, torsion, etc.) to test which material parameters. Basic requirements using this approach is that the specimen stress, strain and temperature uniformity.
