The development of the method for identifying the hardening curves of materials based on the results of torsion tests of notched specimens

The article is devoted to studying the rheological properties of metals and alloys in a cold state. method proposed identify hardening curve material based on torsion tests round specimens with notch. Determining measuring coordinates points surface specimen after testing determining corresponding value torque. Based these values coefficients an equation for stress-strain dependence can be determined by minimizing derived functional. paper proposes algorithm numerical implementation new identification method. results computer simulation confirmed its effectiveness.
