보강판의 균열거동해석과 Crack Arrest 설계(II) - Crack Arrest 거동의 시뮬레이션

Crack Growth Analysis and Crack Arrest Design of Stiffened Panels(II) - Numerical Simulation of Crack Arrest Behavior

To demonstrate the feasibility of utilizing FCAD chart proposed in our previous work, series of crack growth/arrest behavior in the integrally stiffened panels were simulated by numerical method using upper mentioned FCAD charts and a new crack growth rate equation. It is concluded that proposed family of FCAD curves, in the form of non-dimensional arrest load ranges, are reliable indicators of fatigue crack growth/arrest behavior of integrally stiffened panels considered here.
