Physics of Failure Based Fault Identification and Control Methods

In this chapter, the process of fault occurrence, common Physics of Failure (PoF) models and visualization models is first introduced. Then based on the fundamental concepts and principles of load-response analysis, the finite element method and simulation based fault identification technology are introduced. Next, the time-varying reliability models are developed from the analysis of the time effect of the PoF models, and the determination methods of these model parameters are developed based on the degradation process. On this basis, the fundamental process and related methods of failure prediction and evaluation are given based on PoF models. And in the end, the PoF based design optimization and fault control methods are introduced.
