Fatique tool sensitivity analysis and design curves.
MetadataVis full innførsel
The paper looks at fatique tool sensitivity analysis and design curves for aluminum high speed crafts. Spectral fatique method developed by Det Norske Veritas was used to achieve the objective. As only limited initial data was available, preliminary fatique analysis was relevant to conduct in order to receive a minimum required section modulus of a hull section. This parameter impacts fatique lifetime and was used as a comparative value in current study.To summarize, the results showed behavior of the minimum required section modulus influenced by different parameters; in addition, several findings were made during the study. All of them are described in Results and Discussion sections. Finally, this thesis contains several recommendations that may facilitate better design results.
