Summary on Grant Application Form |
|
Prior loading such as proof loading, post weld heat treatment, material ageing and subsequent loading history can have a significant influence on material behaviour. In many structures, prior loading will also have a strong influence on both the residual stresses and fracture toughness. However, it is not known whether these effects are exclusive or additive, particularly in the context of a probabilistic analysis. Quantifying these effects of prior loading will provide improved confidence in determining the continued availability of the structure. Also the use of a probabilistic analysis provides quantitative information about the likelihood of the onset of failure taking into account uncertainties in input data. This joint project between Bristol University and TWI aims to provide a model to quantify the effects with some experimental verification. The project will also to conduct case studies in order to develop general guidelines for structural integrity assessments.
