Temperature-NonThermal Relationship Introduction

When temperature and a second non-thermal stress (e.g. voltage) are the accelerated stresses of a test, then the Arrhenius and the inverse power law models can be combined to yield the temperature-nonthermal (T-NT) model. This model is given by:

(1)     

where,

·        U is the non-thermal stress (i.e. voltage, vibration, etc.),

·        V is the temperature (in absolute units)

and,
