| Abstract: | Based on the Weibull distribution assumption of stress amplitude for long period,the S-N curve of structural material and miner criterion of linear accumulate damage ,a hybrid method which combines the numerical method and analytic method is introduced to estimate the fatigue life of ship structure under fatigue loading. An example for analyzing the structure of a 34,000 dwt lakes type bulk carrier is carried out,the result shows that this method is pratical and effective for ship structure fatigue analysis. |
