응력비의 영향을 고려한 알루미늄합금 A5083-O의 피로균열전파 특성 예측모델
A Model Estimating the Ratigue Crack Growth in Aluminum Alloy A5083-O Considering the Effect of Stress ratio
초록
In this paper the effect of stress ratio on the fatigue crack growth rate of aluminum alloy A5083-O was examined. The fatigue tests were carried out using CCT (center cracked tension) specimens and CT(compact tension) specimens which were subjected to 0.5 and -1.0 stress ratio respectively. The obtained results are as follows; 1) The
