Weibull distribution exponent

Here A p) is a function of the disorder concentration p, the power m is called the Weibull modulus, Tf is the fracture exponent and c and are constants. The first distribution (3.18a) is called the Weibull distribution, while the other one is called the Gumbel distribution. 

The time Weibull modulus depends only on the slope of the flaw distribution (which is given by the Weibull modulus and the SCCG exponent). 

This actually indicates how the dispersion of experimental data varies as inverse function of stress level, very large for low stress and lower for higher stress level. This circumstance is clearly indicated by the probability distribution of Fig. 4.26. The following table lists the scale factor, the Weibull exponent m,...
