| Abstract: | The low-cycle fatigue problem of submarine pressure hull is analyzed in this paper. The residual fatigue life at the calculation point within the cone-cylinder of submarine pressure hull is estimated with the use of Bayesian method, a theory of probability. This provides a new approach of statistical inference without enough information and can make up the disadvantage of classical method to some extent. |
