Abstract : Hot-rolled and annealed 70-30 Cupro-Nickel alloy was tested by completely reversed deflection and zero-to-maximum deflection cycling in the low-cycle fatigue range. It was found that the fatigue life is solely dependent on total strain range. Neither large-mean tensile strains nor compressive strains affect the low-cycle fatigue life. Post yield strain hardening is appreciably greater under cyclic conditions than under static bending or tension. (Author)
