Reliability assessments based on physics-of-failure methods incorporat
e reliability into the design process to prevent parts from failing in
service. An understanding of the physics-of-failure is necessary in a
pplications that afford little opportunity for testing, or for reliabi
lity growth. This paper presents an overview of physics-of-failure and
a case study of the application of physics-of-failure to a specific f
ailure mechanism called conductive filament formation.
