Fatigue Life Prediction Model of 12% Cr Rotor Steel
12% 크롬 로터강의 피로수명 예측 모델에 관한 연구
Abstract
By examining the fatigue deformation properties of 12% Cr rotor steel which has been proved to have high fatigue and creep rupture strength around 600deg. C, authors reviewed major fatigue life prediction models such as Manson, Langer and Morrow equations, and following results were obtained. (1) A simple life prediction model for 12% Cr rotor steel was obtained as follows : DELTA..epsilon.
