Abstract

Physics-of-failure (PoF) for reliability is the application of knowledge of physical degradation processes in products for determining the life expectancy of a product under specified conditions. Central to this approach is the documentation of expected environmental stresses and the identification of failure modes, failure locations, and failure mechanisms that occur within the product. Physics-based models, which equate time to failure due to identified failure mechanisms, are used to quantify life expectancy and prioritize failures. ...
