Subject: Acceleration Factor (AF)
Message:
Greeting: Where can I get the equations of AF under different accelerated stress conditions and/or different dominant failure mechanisms? For example, for thermal fatigue, AF=(delta Ta / delta Tu)^m; for vibration fatigue, AF=(Ga/Gu)^m. Are these correct? And how to determine the index m. I find there are huge differences in m among different resources. Could I find some references which provide better equations and their parameters? Thanks a lot.
