The Accuracy of Failure Predictions Based on Weibull Statistics

摘要

The mechanical failure of ceramic materials is usually characterised by probability equations based on Weibull's weakest link theory. To evaluate these for components in a varying stress field, postprocessors have been developed by us as well as others. The effect of the errors which arises from the postprocessing on the fractional errors in the nominal failure load, the probability of failure or the probability of survival are found and discussed.
