Biography
Professional biography
Richard completed his PhD on additive manufacturing of nickel superalloys at the University of Manchester in 2010 and then as a PDRA he worked on low temperature transformation welding materials also at the University of Manchester. In 2011 he moved to The Open University where he was appointed lecturer in Materials Engineering and in 2015 Senior Lecturer. His research interests include Neutron Diffraction, Synchrotron X-ray Diffraction, Aperiodic metamaterials, Residual stress analysis and Metallurgy.
Research interests
Richard’s research interests hinge around the use of diffraction and optical techniques to develop understanding of residual stress, phase transformations or mechanical behavior of materials. This work often involves the use of large scale national and international research facilities such as ISIS and Diamond in Oxfordshire and the ILL and ESRF in Grenoble, France.
As well as Diffraction techniques, Richard regularly uses the Open University characterization facilities, such as EBSD and digital image correlation to support his research.
Projects
Contour Method Software Development (XD-12-041-RM)
The Contour Method is a destructive method of residual stress characterisation that involves back-calculating the stresses required to cause small elastic distortions in a surface induced by cutting a component into two halves. Although the theory of this method is quite straightforward processing of raw measurements of displacement in a reliable manner is not a trivial task. Furthermore, current software employed in academia is restricted by licence for use in non-commercial work and this limits consultancy work that can be undertaken. The project will involve consolidating two computational methods, one developed by the OU and one by the University of Manchester, into a single software package, using a programing language that doesn't restrict the commercial exploitation of the method. A consultant, namely Mike Fox, who is a scientific software expert, will undertake the majority of the work, with support from Richard Moat.
Novel superior materials based on aperiodic tilings
The proposed research aims at laying the mathematical foundations for aperiodic tiling - inspired structures to be used for additive manufacturing of novel cellular materials. http://www.open.ac.uk/r...ructures-inspired-maths
EPSRC Centre For Doctoral Training (CDT) - Nuclear Energy
An existing CDT led by the Centre for Nuclear Engineering (CNE) at Imperial College in collaboration with multi-disciplinary nuclear groups at Cambridge (Nuclear Energy Centre, CNEC) and The Open Universities, is now joined by the University of Bristol and Bangor University to form a new Nuclear CDT, bringing together over 50 academics with internationally-leading research across nuclear materials (e.g. primary circuit structures, fuels, structural materials and wasteforms), joining/manufacturing technologies, structural integrity assessment methods and standards, thermal hydraulics, geological storage and disposal (e.g. rock mechanics), safety and security (e.g. accident modelling and structural integrity), nuclear technology policy and public engagement, plant decommissioning and clean up, regulation, new nuclear build, advanced reactor technology, the fuel cycle, plant life extension, and naval nuclear propulsion.
