Metallic materials — Fatigue testing — Axial-strain-controlled method

ISO 12106:2017 specifies a method of testing uniaxially deformed specimens under strain control at constant amplitude, uniform temperature and fixed strain ratios including at R_e = −1 for the determination of fatigue properties. It can also be used as a guide for testing under other R-ratios, as well as elevated temperatures where creep deformation effects may be active.
