Zusammenfassung:A method for low-cycle environment fatigue test using small fatigue specimen is provided to use in additional environment fatigue life valuation curve development research. A method for low-cycle environment fatigue test using small fatigue specimen comprises: a step(ST1) measuring the transformation ratio of an LVDT(Linear Variable Differential Transformer) and an extensometer; and a step(ST2) grasping the displacement of the auto clave inside the LVDT of the PWR experiment environment by using the measured transformation ratio of the LVDT and the extensometer. The displacement and the transformation ratio are measured by a displacement sensor of the LVDT formed outside the real gage of small fatigue specimen.
