Abstract
For enabling a calculation of the force and work requirement of metal forming processes and the strain hardening of the material from the flow curve obtained by any experiment /4.1, 4.2/, the test conditions must simulate those of the actual metal forming process. This holds both for parameters like temperature, strain rate and the state of stress and for the specimens which shall be representative of the material or to be formed. The problems arising from these basic requirements shall now be discussed in detail. It should be taken in mind, however, that besides these basic requirements the number, size and location of specimens may also be determined by product specifications for the material to be tested.
