There are many countries in the metallurgy, machinery manufacturing, defense industry with a forging machine for the production of alloy steel, high-strength steel, titanium and alloy products difficult deformation world. Forging machines with different types of ingots or billets respectively forged into bars, round, square, rectangular section or forging into rotational symmetry axis, solid shaft and hollow stepped shaft, taper shafts, thick-walled tube, barrel, etc. Some countries in order to expand the product range gear axle, using a hydraulic forging press and forging machine joint operations, there is also the size of the forging machine joint operations. Since the 1970s axle gear manufacturers, forging process and the development of forging - rolling process, and the creation of forging - rolling mill group, which consists of a multi-hammer forging machine after continuous rolling mill with a number consisting of large rotary Kiln gear wheel bearing selection, mainly used in steel plant small bar. 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 relation, 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.
