Abstract Delayed fracture in brittle materials may be demonstrated by observing the change in bend strength over a range of constant stress rates to failure. A simple technique has been developed to analyse this behaviour making efficient use of the experimental data. Based on a model incorporating theories of stress corrosion and brittle fracture, with Weibull statistics, the technique provides estimates of relevant parameters using the method of maximum likelihood. Confidence intervals of estimates, the significance of any observed rate effect, and the validity of the model are also assessed. The technique is demonstrated by applying it to data from bend tests on soda-lime glass and WC-Co materials.
