Professional biography

 

I graduated in Mechanical Engineering (1976) and obtained an MSc in Physics of Materials (1977) at the University of Bristol. My first appointment for a Civil Engineering Consultancy broadened my engineering horizon before joining Rolls-Royce (1979) and specialising in stress and fracture analysis of rotating gas turbine components. From 1986 to 2008 I worked in the nuclear power generation industry in the field of structural integrity (supporting safety cases) and became recognised as the company residual stress expert. From 1995 onwards I initiated and managed many industry and EU funded structural integrity related research projects. In 2007 I was awarded a Royal Society Industry Fellowship and appointed Professor of Materials for Energy at the Open University in 2008. Since coming to the OU I have raised external income exceeding £2.5m (EPSRC, Royal Society, EMDA, industry) and doubled the number of researchers and laboratory facilities of the Materials Engineering Group which currently comprises 11 academics, 15 PhD students and 5 post-doctoral researchers. 

 

Research interests

The safe operation of engineering structures is vital in safety critical industries. Structural integrity failures can have catastrophic consequences in terms of loss of life and financial circumstances. Meanwhile there is a strong interest in reducing costs, light-weighting, increasing design life and life extension. To this end reliable structural assessments are essential at the design stage and through in-service life to ensure continuous profitable operation of assets. Residual stresses are inevitably introduced in engineering structures during manufacturing processes. Their presence can have adverse effects on the behaviour of structures and contribute to driving force promoting degradation mechanisms including crack initiation, crack growth, stress corrosion cracking, fatigue and fracture. Therefore it is of paramount importance that the state of residual stresses in engineering structures is carefully and reliably characterised so that remedial actions could be taken to enhance the lifetime of current materials or novel designs and manufacturing methods developed and optimised. For the first time, this project proposes novel advances that will radically bring new capabilities for the contour method of residual stress measurement in several ways: it will unlock maps of residual stress in multiple directions simultaneously. Of a true step change is extending the application of the technique to measure 3D maps of residual stress. The application of novel advances enables the technique to be implemented on complex engineering structures. The proposed research has the potential to provide far more complete residual stress information about safety critical components of high interest to engineers in the aerospace, petrochemical, power generation and nuclear industries.

OU CDT Equipment

Lead01/Oct/201430/Sep/2019EPSRC (Engineering and Physical Sciences Research Council)
One of our specialist capabilities is application of DIC to measure inhomogeneous deformation (e.g. of weldments) at room temperature and creep deformation behaviour up to 1000C. We plan to upgrade two of our standard creep machines to allow DIC monitoring (one machine for 3D DIC and the other for creep crack growth testing) for use of CDT students. The equipment will comprise 2 DIC upgrade system packages. 1) New furnace with access window for 3D DIC monitoring, 2 high resolution cameras & bellows, mounting table and lighting. 2) New furnace with large access window for CT crack growth monitoring, 1 high resolution camera & bellows, DC PD unit for crack growth, mounting table and lighting. The equipment will be installed in our main creep laboratory.
