In the process of fatigue research, it is found that most of the fatigue life data of structures conform to Weibull distribution rather than Gaussian distribution, and Weibull distribution is in a sense more general distribution than Gaussian distribution. But the biggest obstacle to the application of Weibull distribution is the complexity of Weibull distribution, especially the estimation of its three parameters is difficult. This is because the correlation coefficient estimation, MLE and other methods proposed by people have a common characteristic that the mathematical derivation is complicated and the calculation is complex. Based on the estimation of the correlation coefficients, author proposed Z.T. Gao method which can avoid these difficulties and can easily estimate the three parameters of Weibull distribution. Further study found that the idea of Z.T. Gao method can be used to avoid the difficulty of MLE, author call it generalized Z.T. Gao method can also conveniently get more ideal results.
