What stresses can use an inverse power model?
It can be appropriate for some voltage, mechanical-load and other stress-driven mechanisms, but applicability and exponent must be established for the mechanism.
Reliability Toolkit
Inverse Power Law Acceleration Factor Calculator
Estimate acceleration when life is modelled as an inverse power of a non-thermal stress such as voltage, load or another mechanism-specific stress variable.
How to use it
Inputs that remain auditable.
- 01
Enter use and accelerated stress in the same units.
- 02
Enter the experimentally justified exponent n.
- 03
Use the equivalent-exposure output only within the validated model range.
Questions
Frequently asked
Should accelerated stress always be higher?
For a conventional acceleration calculation it normally is. If the entered accelerated stress is lower, the resulting factor will be below one.
