| Abstract: | Life scatter factor methods for disk probabilistic life assessment based on Weibull and Logarithm normal distributions were discussed first.Then two improved life scatter factor methods were proposed for probabilistic life experimental assessment of a disk with multi critical sites.A numerical example of disk life assessment was given to demonstrate the application of the improved assessment methods. |
