Template:Eyring-weib mean

Mean or MTTF
The mean, $$\overline{T}$$, or Mean Time To Failure (MTTF) for the Eyring-Weibull model is given by:


 * $$\overline{T}=\frac{1}{V}{{e}^{-\left( A-\tfrac{B}{V} \right)}}\cdot \Gamma \left( \frac{1}{\beta }+1 \right)$$

where $$\Gamma \left( \tfrac{1}{\beta }+1 \right)$$  is the gamma function evaluated at the value of  $$\left( \tfrac{1}{\beta }+1 \right)$$.
