Aplicação do método de análise espectral na avaliação do dano à fadiga em estruturas navais

Abstract

This work aims to demonstrate the application of the spectral analysis method in the evaluation of the fatigue damage in naval structures. For this, the theoretical concepts are presented first, which are the basis for the understanding of the method. Then, the methodology, through which this work was developed, is described. Finally, the applicability of this method is exemplified by the case study where a hypothetical scenario is considered in which the possibility of moving a vessel from its original area of operation to another area is verified, and a comparison is then made of the results in terms of accumulated fatigue damage. The analysis model was consistent, yielding results consistent with reality.
