Generalized Eyring Relationship Introduction

The generalized Eyring relationship is used when temperature and a second non-thermal stress (e.g. voltage) are the accelerated stresses of a test and their interaction is also of interest. This relationship is given by:

(15)
 

where:

• V is the temperature in absolute units (i.e. degrees Kelvin or degrees Rankine).

• U is the non-thermal stress (i.e. voltage, vibration, etc.).
• A, B, C, D are the parameters to be determined.

The Eyring relationship is a simple case of the generalized Eyring relationship where C = D = 0 and  AEyr = -AGEyr. Note that the generalized Eyring relationship includes the interaction term of U and V as described by the term. In other words, this model can estimate the effect of changing one of the factors depending on the level of the other factor.
