A Critical Evaluation of Weibull Accelerated Failure Models

Abstract The life of a component depends on the stress on the component. Many different stress-life models have been proposed, and lots of test data reported, in the literature. In this paper we look at stress-life data for mechanical components and characterise the salient features of different empirical plots of test data. We evaluate three Weibull accelerated failure models by comparing the empirical plots (derived from test data) and the theoretical plots (derived from model analysis) and suggests topics for future research.
