Garbatov, Y. e Guedes Soares, C. (2001), “Fatigue Reliability Analysis of a Corner of the Hatchway of a Bulk Carrier” , Proceedings of the III Meeting of Metal and Mixed Structures, 6-7 Dezembro, Aveiro, Portugal, pp. 553-562

The work presented here analyses the reliability of a welded structural joint of a bulk carrier with respect to fatigue crack growth. The crack is assumed to appear after a random period of time at the corner of the hatchway. The model applied describes the crack growth as a time dependent function using linear fracture mechanics. Long-term stress range response of the welded joint is calculated based on the combination of the global and the local loading. Fatigue reliability is predicted based on a time variant formulation and the effect of repair and maintenance is also quantified. global and the local loading. Fatigue reliability is predicted based on a time variant formulation and the effect of repair and maintenance is also quantified.
