Abstract

Abstract

Weibull shape coefficient k that is decided by ship's length and wave height is very important for studying ship's fatigue strength.Using the coefficient k, an example ship's fatigue life was calculated.It is pointed out that the calculated results have a great error compared with actul case.To reduce the error and calculate fatigue life accurately, the uniform function of coefficient k based on accumulated damage model must be developed according to ship's actul case.
