The Effect of Stress Ratio on Fatigue Crack Propagation Rate in SA516/70 Pressure Vessel Steel at Low Temperature
SA516/70 압력용기 강의 저온 피로균열 진전 속도에 미치는 응력비의 영향
Abstract
The fatigue crack growth behavior of the SA516/70 steel which is used for pressure vessels was examined experimentally at room temperature,
