Comparison between residual stress induced by waterjet peening and shot peening (2016)
Presentation / Conference Contribution

Surface modification techniques have received much attention among the researchers around the world. Yet, finding the best way to enhance the surface properties remains one of the challenges in engineering. Most of the fatigue cracks begins from the...

Effect of gauge volume on the residual stress measurement using deep hole drilling technique (2010)
Presentation / Conference Contribution

Accurate evaluation of residual stress is essential if is to be taken into account in structural integrity assessments. For thick components, many non-destructive residual stress measurement techniques cannot be used since they are unable to measure...

Application of the modified deep hole drilling technique (iDHD) for measuring near yield non-axisymmetric residual stresses (2010)
Presentation / Conference Contribution

The modified deep hole drilling technique (iDHD) has been developed to allow near yield residual stresses to be measured and has been validated for axisymmetric residual stress fields. In the present investigation, the application of the iDHD techniq...

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.

Generating well defined residual stresses in laboratory specimens (2008)
Presentation / Conference Contribution

Residual stresses play an important role in increasing and decreasing the possibility of failure. The magnitude and direction of the residual stresses is an important factor in the integrity of engineering structures, including those containing defec...

Measurement and prediction of residual stress generated by local compression (2003)
Presentation / Conference Contribution

In order to assess the effect of a residual stress field on the fracture behaviour of materials, a well-defined residual stress field, with known characteristics, such as triaxiality, must be generated in a controllable and reproducible manner. In th... Read More about Measurement and prediction of residual stress generated by local compression.

Influence of residual stress on the fracture behaviour of an aluminium alloy (2003)
Presentation / Conference Contribution

Influence of residual stresses on fracture response of an Aluminum alloy is investigated. Cylindrical flat ended punching tools are employed to introduce residual stresses on 15mm thick C (T) specimens. The residual stress field resulting from Local...

Combined effect of residual stress and loading history on brittle fracture (2003)
Presentation / Conference Contribution

The aim of this paper is to examine the influence of residual stress (RS) and loading history on the subsequent low-temperature cleavage fracture resistance of ferritic steel structures such as pressure vessels. Three dimensional finite element analy... Read More about Combined effect of residual stress and loading history on brittle fracture.
