====Arrhenius-Weibull Reliability Function====
#REDIRECT [[Arrhenius_Relationship#Arrhenius-Weibull_Statistical_Properties_Summary]]
<br>
The Arrhenius-Weibull reliability function is given by:
 
<br>
::<math>R(T,V)={{e}^{-{{\left( \tfrac{T}{C\cdot {{e}^{\tfrac{B}{V}}}} \right)}^{\beta }}}}</math>
 
<br>
If the parameter  <math>B</math>  is positive, then the reliability increases as stress decreases.

<br>
The behavior of the reliability function of the Weibull distribution for different values of  <math>\beta </math>  was illustrated [[Distributions used in Accelerated Testing#The Weibull Distribution|here]]. 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 the next figure is now needed to illustrate the effects of both the stress and  <math>\beta .</math>
