Guidelines for physics-of-failure based accelerated stress testing

A systematic accelerated stress testing approach, based on physics-of-failure (PoF) principles is presented for the reliability assessment of an avionics electronic module. Results from this case study demonstrate that combined accelerated stress tests may produce complex synergies that can only be controlled through precise PoF assessment. The paper concludes with a set of generic guidelines to design, plan, conduct and successfully implement PoF based accelerated stress tests.
