Experimental determination of Weibull parameters for a fiber

A statistical analysis of the liber tensile strength values determined on a series of fiber samples can be easily made by using the two-parameter Weibull distribution described above. Using the form of the Weibull expression given in Eq. (10.2), we can write the probability of failure F(o) of the liber at a stress a, as 

The Weibull mean tensile strength, a-, standard deviation, s, and coefficient of variation (CV) can be obtained
