A comprehensive numerical study has been carried out to investigate

and to explore the impact of the presence of part through surface cracks of various

size and orientation in a thick welded ferritic steel ...

Based on the traditional definitions associated with creep strain accumulation in defect free components, a generalised definition for “elastic follow-up” factor, Z is proposed that characterises the impact of a “nonlinear” ...

Local stress based approaches to fracture prediction use Weibull distribution model based on weakest

link theory. Accuracy of predictions as part of the integrity assessment of structural steels containing

defects ...

This paper reviews the concepts and definitions related to elastic follow-up, Z, together with its potential use in stress classification. Based on the principles governing benchmark multiple bar structures elastic follow-up ...

A comprehensive numerical study has been carried out to investigate and to explore the impact of the presence of part through surface cracks of various size and orientation in a thick welded ferritic steel cylindrical ...

One critical issue in the integrity assessment of pressurised vessels to be addressed is characterising the influence of initial residual stresses (arising from fabrication processes especially around welds, where the ...

In this paper finite element simulations of fracture tests are carried out firstly to verify the experimental findings and secondly to examine and validate the proposed Global equations. This objective has been achieved ...

Application of combined loading to a defect free cylinder would result in two situations; a) fully elastic under internal pressure and reach the limit state by application of additional axial force, and b) the internal ...

A unified framework for quantification of elastic follow-up is provided by using simplified benchmark models that ideally represent the behaviour of real structures. Closed form analytical solutions for evaluation of EFU ...
