A Strength-Stress Interference Model for Time-Varying Probability of Failure and Its Application to an Electromechanical System.
Abstract
In electromechanical systems, failure can be represented as the application of a stress to some component which exceeds the corresponding strength of that component. In general, both the stress and strength will be random variables. Aging, wear and overstress conditions can then be considered as phenomena which cause time variation of either the stress or the strength distribution for a particular failure mechanism. The research presented in this thesis develops probabilistic models for the time variation of stress and strength distributions due to these effects, thus permitting prediction of probability of failure as a function of time without a priori knowledge of system failure statistics.
