A recent advance in the assessment of creep rupture data Original Research Article

A new procedure for the assessment of creep rupture data has been developed in the UK. The methodology features a state-of-the-art statistical treatment with independent checks on the physical realism, goodness of fit and extrapolation repeatability/stability of the model equation established to best characterise the behaviour of the material under investigation. Software provides semi-automation to allow full advantage to be taken of modern desk top computing power, but with ample provision for expert-user intervention. The paper reviews the background knowledge which underpins the new procedure and illustrates the method of implementation.
