Description
- The principal aims of this fellowship are to develop more advanced structural integrity assessment methods and to exploit recent advances in machine learning to identify and predict key parameters influencing transformative damage in fracture toughness testing. The benefits of this work include significant industrial cost savings through enhanced component design, reduced maintenance cost and reduction in early structure retirement.

Increased healthcare demand is significantly straining European services. Digital solutions including advanced modelling techniques offer a promising solution to optimising patient flow without impacting day-to-day healthcare provision. In this work we outline an ongoing project that aims to optimise healthcare resources using agent-based simulatio...
In this paper, we carefully develop a finite element (FE) model that gives accurate through-thickness predictions of stress and strain distributions during the steady-state cold rolling process. These through-thickness predictions unveil an oscillatory pattern that is shown to have important consequences for residual stress in the rolled sheet. We...
A new semi-analytic model of the metal rolling processes is presented and validated against finite element simulations. The model generalizes the classical Slab Method of cold rolling, and for the first time is able to predict the through-thickness stress and strain oscillations present in long-aspect-ratio roll gaps. The model is based on the asym...
The finite element (FE) method is a powerful tool for simulating industrial metal forming processes such as metal rolling. FE allows users to estimate the stress distribution in the metal sheet during the rolling process. However, FE simulations do not allow for real-time online process control due to model complexity and computational time. This p...
In this work, a new mathematical model for cold rolling processes is presented. Starting from the governing equations and assuming only a narrow roll gap aspect ratio (in effect, large rolls on a thin strip), we find a solution by introducing two length scales inherent to the problem. The solution consists of a large scale, along with small (next o...
Quantifying the relationship between crack tip constraint and fracture toughness is key to improving the structural integrity assessment of critical infrastructure. The role of in-plane and out-of-plane constraint on fracture toughness requires greater understanding, particularly for low strength materials where test data are limited. In this work...
Friction stir welding induces a relatively low level of deflection, and residual stresses and recent advances in the welding technology has shown that friction stir welding may now be broadly used in steel welding leading to significant improvement of the welding quality for new constructions and repairs. In the present study experimental and numer...
The structural integrity of pressure vessels (PVs) is controlled by the application of various design and fabrication codes and standards. Within the European single market (ESM) design codes exist at both a European and a national level which can lead to variability in design procedures. The European standard EN 13445 has been updated several time...
Dissimilar Metal Welds (DMWs) are used in many industries to increase the service life of components. Typically a corrosion resistant material is bonded to the internal surface of a
second material, this is often referred to as cladding. This type of composite component provides the desired mechanical properties and corrosion resistance without exc...
Dissimilar Metal Welds (DMWs) are used in many industries to increase the service life of components in corrosive environments. Structural integrity assessments of these components are complicated due to the changes in microstructure and difficulties in estimating defect location and size. The interaction between primary and secondary stresses on c...
Life extension of ageing assets is becoming increasingly important for the offshore oil and gas industry. Many pressure vessels in service have reached or are about to reach the end of their design lives, but their continued operation is required until the economic field life is exhausted. Many vessels in-service were designed over 30 years ago, wh...
