Arrhenius Method
Parameters required for the Arrhenius method include activation energy, K factor, and temperature values. If these values are known, you can use the Arrhenius method to compute the failure rate for the user-defined part.
1. For Failure Method, select Arrhenius. The parameters under -- Arrhenius -- become available.
2. Complete these parameters.
