Garbatov, Y. e Guedes Soares, C. (2012), “Uncertainty Assessment of Fatigue Damage of Welded Ship Structural Joints”, Engineering Structures, Vol. 44, pp. 322-333

The objective of this work is to study the effect of various factors related to fatigue damage assessment. Fatigue life is predicted by S-N approach based on the long-term stress range. The work analyses the importance and interaction between various factors including ship main characteristics, operational profile based on a mission or loading condition, wave spectra, heading distributions and take into account the random origin of mean stress effect, imperfection, weld shape improvement, hot-spot calculation and resulting a notch stress concentration factor to fatigue life of a but welded ship structural component.
