Accelerated Degradation

  • J.W. McPherson


Generally, materials/devices exist in metastable states. These states are referred to as being metastable because they are only apparently stable. Metastable states will change/degrade with time. The rate of degradation of the materials (and eventual time-to-failure for the device) can be accelerated by an elevated stress (e.g., mechanical stress, electrical stress, electrochemical stress, etc.) and/or elevated temperature.
