The greater the inhomogeneity of the material parameters measured error greater. At high temperatures when considering changes in microstructure, to be completely uniform microstructure of the specimen is very difficult, but due to the non-linear clearance forging microstructure and macroscopic deformation changes between the microstructure of the spatial distribution of the small differences can cause very different macroscopic stress-strain of Luoyang good Forge, the same macroscopic inhomogeneity of deformation microstructures can also cause more uneven. Chinese scholars have recently proposed a combination of experimental and finite element sub-iteration method. Convergence criterion of this approach is the finite element calculation results and experimental results of the difference is less than some small constant. This method is calculated from the test results of the initial value of the parameter of the first material in a conventional manner. Then substituted into the finite element simulation program testing process forging prices and to fix these parameters based on the difference between the calculation results with the experimental results. Compared with ordinary numerical method to substitute the law, due to the impact of various parameters on the test results for each physical relationship is very complex, so the correction formula is much more complex. This theoretical research currently underway iterative approach. Forging manufacturers, forging, forged by Luoyang Super League Super League Forging Limited. Luoyang Super League Forging Co., Ltd.
