Arrhenius-Exponential Model

This example validates the calculations for the Arrhenius-exponential model in ALTA standard folios.

The data set is from Example 7.1 on page 254 in book Life Cycle Reliability Engineering by Dr. Guangbin Yang, John Wiley & Sons, 2007.

For this data set, the Arrhenius life-stress relationship with an exponential distribution is used. The estimated activation energy value is $$\,\!E_{a}=0.323$$. The acceleration factor from 70°C to 35°C is 3.5.

In ALTA, the temperature values given in the book are converted from Celsius to Kelvins, as shown next.



The calculated activation energy is 0.323. The acceleration factor from 70°C (343.15 K) to 35°C (308.15 K) is 3.46 as shown next.
