... model are elaborated and, as a result, a relatively simple formula is proposed to calculate the minimum bending radius from the reduction in the area at fracture, the strain hardening exponent, and the yield stress, which are material parameters available from tensile tests. For this purpose, a finite...

... is only affected by resistive heating, does not compare with the plot obtained experimentally. This is because of the presence of the electron flow during the test. While the modulus of elasticity and elongation are approximately the same between the two tests, the yield stress and flow stress...

... in the dislocation density. Fatigue strength was improved by deformation rate (i.e., rolling speed), which is also due to the increasing dislocation density. Yield stress of the studied specimens followed the same pattern as fatigue strength. Considering the obtained results from the low and high speed, partial...
