Application of the local approach to predict load history effects in ferritic steels (2008)
Presentation / Conference Contribution
The effect of residual stresses on fracture behaviour of ferritic steels at low temperature has been investigated using a local approach based on the Beremin model [1]. The study aims to enhance the use of local approach in failure prediction when re... Read More about Application of the local approach to predict load history effects in ferritic steels.
J-integral and CMOD for external inclined cracks on autofrettaged cylinders (2011)
Journal Article
Autofrettage is a well-known method to increase the load carrying capacity of the pressure vessels. The autofrettage outcomes can be contrary when the imperfections or material discontinuities are on the outer surface. In this study, the influences o...

A novel method to determine material properties and residual stresses simultaneously using spherical indentation (2014)
Journal Article
Spherical indentation is one of the non-destructive techniques that has gained great interest among researchers in recent years. Spherical indentation is inexpensive and quick and can provide a fairly accurate estimation of in-plane residual stresses...

Accurate measurement of highly triaxial residual stresses
Presentation / Conference Contribution
Accurate measurement of residual stress is essential if account is to be taken of residual stress in structural integrity assessments. For thick components many non-destructive residual stress measurement techniques cannot be used since they are unab... Read More about Accurate measurement of highly triaxial residual stresses.
Experiments and predictions of the effects of load history on cleavage fracture in steel (2009)
Journal Article
A series of experiments conducted on two steels, A533B and A508, are summarised. Tests were conducted to explore the influence of different room temperature pre-loading cycles on subsequent low temperature (−150 °C and −170 °C) cleavage fracture. In...
