AbstractIn this work we measure and estimate, experimentally and numerically, approximate fatigue strengths of steel filaments of 0.25 mm diameter with 80% C by the pure bending test method. All fatigue tests have been realized at room temperature and at a frequency of 10 Hz via a custom manufactured pure bending tester of which the fully reserved strain value, R = εmin/εmax, is −1. The applied value of cyclic deformation, ε, has been chosen from the range 0.46-1.07. The plots of S-N (Strain–Cycle) curves are based on high fatigue cycle (HFC) lives that are greater than or equal to 106 cycles.
