Fe-18Mn TWIP강의 Pre-strain에 따른 저주기 피로 수명 예측 모델 연구
A Prediction Model for Low Cycle Fatigue Life of Pre-strained Fe-18Mn TWIP Steel
초록
The influence of pre-strain in low-cycle fatigue behavior of Fe-18Mn-0.05Al-0.6C TWIP steel was studied by conducting axial strain-controlled tests. As-received plates were deformed by rolling with reduction ratios of 10 and 30%, respectively. A triangular waveform with a constant frequency of 1 Hz was employed for low cycle fatigue test at the strain amplitudes in the range of
