Abstract
In the design of metalworking technologies, one of the most important amount is the flow stress of the material. A few experimental method can be used to measure it. The most commonly used tests to determine the flow curve of materials include upsetting of cylindrical or prismatic specimens, tension or torsion tests. In our work, the determination method of flow curve were investigated based on the principle of virtual power with cold working conditions. The experimental method, cylindrical upsetting, was executed on the Gleeble 3800 thermo-mechanical simulator. The goal was to determine reliable flow curve for large plastic strain. The results showed that reliable flow stress values were obtainable in equivalent plastic strain range of 0 to 0.7 by continuous cylindrical upsetting.
