| ====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.

| 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>
