Arrhenius-Weibull Reliability Function
The Arrhenius-Weibull reliability function is given by:


 * $$R(T,V)={{e}^{-{{\left( \tfrac{T}{C\cdot {{e}^{\tfrac{B}{V}}}} \right)}^{\beta }}}}$$

If the parameter $$B$$  is positive, then the reliability increases as stress decreases.

The behavior of the reliability function of the Weibull distribution for different values of $$\beta $$  was illustrated in Chapter 5. In the case of the Arrhenius-Weibull model, however, the reliability is a function of stress also. A 3D plot such as the ones shown in Fig. 8 is now needed to illustrate the effects of both the stress and $$\beta .$$
