Value: £60,000

Summary: The main purpose of my Royal Society Wolfson Merit Award is to seek better ways of ensuring longer survival of highly valued engineered parts. Examples of engineered parts include pressurised pipes used in power generation and rotating machinery such as turbines. In particular, I seek to establish methods whereby the locked-in stresses in the parts can be measured. In addition I wish to establish how we can take account of all events seen by the engineered part and this is usually termed as providing information about the loading history of the part. My activities in the 12 month period April 2011 to end of March 2012 have focussed on strategic growth and research to underpin ensuring longer term survival of engineering components. Growth has been centred on launching a new Bristol-Oxford Nuclear Research Centre on 8 November 2011. Extensive networking has led to consolidating research topics with key governmental agencies and industrial companies involved in Nuclear Engineering. In addition I have been able to consolidate our research into the performance of high temperature materials that are being used in the current generation of nuclear power systems. This materials understanding is used to underpin routes to extending the life of the UK nuclear fleet. The high temperature materials research has also been discussed and promoted through various Bristol led workshops and allows us to link high temperature materials research activities widely in the UK. Research results have been widely reported by our group at a variety of conferences including topics on creep and fracture of materials, and modelling and measurement of residual stresses. A new Research Chair to support my activities from 2012-2017 has been awarded by the Royal Academy of Engineering, EDF-Energy and Rolls-Royce.
