| Abstract: | A general form of the permissible stress range criterion for fatigue strength of shiphull structures in derived in this paper. On this basis, the permissible "once in a life"stress range criterion is also derived, which is under the assumption that the long term distribution of the stress range is Weibull type. Some of the influence factors and the calculation of the design stress range are discussed. The emphasis is laid on the fatigue strengthassessment of container ships. A numerical example is given. |
