Garbatov, Y., Rudan, S. e Guedes Soares, C. (2002), “Application of the Spectral Approach for Fatigue Analysis of Marine Structural Details”, Proceedings of the 10th International Congress of the International Maritime Association of the Mediterranean (IMAM´02), 13-17 Maio, Rethymno, Crete-Hellas
The paper focuses on the evaluation of the fatigue life of marine structural details. The fatigue life is predicted based on a probabilistic approach that properly considers the stochastic nature of the ocean environment and the service profile of the structure. The approach includes generation of a stress range response function calculated by a finite element model. Considering the loading process as narrow-band for each short-term sea state a Rayleigh distribution for stress amplitude is calculated. Then the long-term stress range response is fitted by a Weibull distribution. The PalmgrenMiner linear cumulative damage model is applied. A comparative analysis with the existing results in the literature is also made.
