Matthew J Doré PhD CEng FWeldI AMICE

Back to Who We Are Alan Taylor Carol Johnson Colin Ribton Dr Channa Nageswaran Jonathan Martin Matthew Doré
 

Matthew Doré joined the Fatigue section at TWI in October 2000. He gained his PhD through The Open University under the supervision of Professor Michael Fitzpatrick and Dr Steve Maddox. The title of his work was, ‘An Investigation of Fatigue Crack Growth Acceleration.’

Matthew is the TWI Technology Fellow in Structural Integrity (Steels), his particular expertise is in fatigue design of welded joints, but he works closely with colleagues involved in all aspects of structural integrity.

Matthew’s research over the last decade in the subject area of fatigue has been broad, considering areas such as variable amplitude loading and in particular load sequence effects, fatigue life improvement through use of high frequency mechanical impact (HFMI) treatment on high strength steels and aluminium alloy,  fatigue of vintage tubular joints, as well as other key areas in fatigue design such as misalignment, bending and thickness effects, fatigue crack growth rate (FCGR), fracture mechanics assessments and the effect of aggressive environments. In addition to this, through his own work and through supervision of PhD students, he has been actively involved in the area of additive manufacturing.

Matthew provides guidance and support to TWI Industrial Members and colleagues alike on issues such as fatigue design, fracture, standards interpretation, residual stress and bridge related studies.  

He has led over 100 projects across oil and gas, construction, renewables, nuclear, defence, shipping, power, off-highway and automotive industry sectors in his 25 years at TWI and contributed to many more as well as undertaking expert witness work. He has also guided several PhD candidates to successful completion of their courses.

Matthew is a Fellow of The Welding Institute and Associate Member of the Institution of Civil Engineers. He is a main committee member of the British Standards Institute WEE/37, Chair of BS 7608, Chair of BS 7910 (fatigue), the UK National Delegate to the International Institute of Welding Commission XIII and committee member of Structural Steel and Bridges B/525/10, CB/203 and CEN. He is also a member of the Lloyds Register Technical Committee (Marine and Offshore) and Principal Reviewer for ‘Welding in the World.’

Matthew has also been involved in instrumental work around fatigue, fracture mechanics and additive manufacturing and has over 20 published articles (see below).
