보강판의 균열거동해석과 Crack Arrest 설계(III) - Crack Arrest Design 차트의 실험평가
Crack Growth Analysis and Crack Arrest Design of Stiffened Panels(III) - Experimental Evaluation of Crack Arrest Design Chart
초록
In order to assess the validity of fatigue crack arrest design charts obtained from our previous numerical approach to fatigue crack arrest condition, an extensive fatigue crack growth/arrest test was performed using CT-type integrally stiffened panels. The results are presented as fatigue crack growth rate and non-dimensional crack length relationship, and these are compared with numerically simulated crack growth rates. The measured values of da/dN at the moment of fatigue crack arrest occurred in stiffened panels are good agreement with those numerically simulated crack growth rates.
