A Model Estimating the Fatigue Crack Growth in Aluminum Alloy A5083-O Considering the Effect of Stress Concentration
응력집중의 영향을 고려한 알루미늄합금 A5083-O의 피로균열전파 특성 예측모델
Abstract
In this study the fatigue crack growth behavior was investigated for the surface cracks in aluminum alloy A5083-O plate and its weldment. Several kinds of specimens were tested at room temperature. The Eccentric specimens(E1.0, E2.5) subjected to combined stresses(tension+bending) were tested and the welded specimens with weld toes(TOE1, TOE2) were tested in order to verify the method to consider the stress concentration such as weld toe. It was ascertained that the surface crack growth property in the weld toe could be predicted by the corrected Pang's equation proposed in this study.
