Corresponds to a Weibull distribution for which parameter β = 1
Model 2 : Normal distribution - the failure appears around a t mean
Corresponds to a Weibull distribution for which parameter β = 3.6
Model 3 : Log-normal distribution - applies to the phenomena of mechanical wear/use
Corresponds to a Weibull distribution for which parameter β = 2.5
