Feng, G.Q., Garbatov, Y. e Guedes Soares, C. (2013), “Fatigue reliability of deck structures subjected to correlated crack growth”, Journal of Marine Science and Application, Vol. 12, pp. 413-421
The objective of this work is to analyse fatigue reliability of deck structures subjected to correlated crack growth. Deck structures are considered as a series system of stiffened panels. The stress intensity factors of the correlated cracks are obtained by finite element analysis and based on which the geometry correction functions are derived. The Monte Carlo simulations are applied to predict the statistical descriptors of correlated cracks based on the Paris-Erdogan equation. A probabilistic model of crack growth as a function of time is used to analyse the fatigue reliability of deck structures accounting for the crack propagation correlation. A deck structure is modelled as a series system of stiffened panels, where a stiffened panel is regarded as a parallel system composed of plate and longitudinal stiffener.
