Abstract:

For estimating the parameters of Weibull distribution in fatigue, the equivalence and relation between Lognormal and Weibull distribution from their characteristic functions are studied. Based on the above studies a new method for estimating three parameters of Weibull distribution has been developed, aad proved to be simple, practical and easy to use.

Key words: fatigue, Weibull distribution, calculation methods
