Fatigue Crack Growth Behavior for Rail Steel under Mixed Mode Variable Amplitude Loading
혼합모드 변동하중하에서 레일강의 피로균열 진전거동
- Published : 2003.04.23
Abstract
The growth behavior of the transverse crack, which was one of the most dangerous damages of rail defects, was investigated under mode I and mixed mode loading in rail steel. In the case of variable amplitude loading, the fatigue crack growth behavior was discussed using characteristic stress intensity factor ranges
