Current interests
Neil McCartney is an Emeritus Senior Fellow in Materials Modelling. Neil's work on continuum modelling of materials includes:
- Modelling of proton exchange membrane (PEM) fuel cells, where multi-physics, two phase and multi-scale continuum modelling is considered. Heat and mass transport modelling is based on the principles of continuum thermodynamics.
- Modelling of multi-layered piezoelectric laminates subject to complex loading involving mechanical, thermal and electrical stimuli. Use of models to develop methodologies for the measurement of piezoelectric properties.
- Prediction of the effective properties of undamaged composites (particle and fibre reinforced) and of undamaged laminates.
- Prediction of the initiation and progressive growth of damage in UD fibre reinforced lamina and general symmetric laminates to the point of failure. (A book on this topic is currently being written.)
- Studying deformation and fracture processes in metals, ceramics, polymers (including multi-layered coatings).
- Fatigue and creep response of metals, polymers and composites.
- A key current area of interest is the identification of reliable methods of linking atomistic models to continuum models, including dealing with the significant problems of the meso-scale arising from the presence of vacancies, dislocations and domains.
In the future he would like to extend the work so that the continuum thermodynamical modelling of interacting mechanical, thermal, electric and magnetic phenomena can be applied at the nano- and meso-scales for a range of important industrial applications.
Biography
Neil received a BSc, MSc and PhD in Applied Mathematics from Manchester University.
He has since worked at NPL, currently as an NPL Emeritus Senior Fellow, acting as a consultant to the Engineering, Materials and Electrical Science Department, where his work includes polymer electrolyte membrane (PEM) fuel cell modelling and the modelling of nanostrain in multi-layered piezoelectric systems subject to complex loading involving mechanical, thermal and electric stimulation.
Neil was Visiting Professor in Dept. of Materials Science and Engineering, University of Surrey, March 1995 to 31 Aug. 2010, and Visiting Professor in Centre for Collaborative Research, The University of Tokyo, Japan, 1 Feb. 1999 - 8 May 1999.
He is a Fellow of the Institute of Mathematics and its Applications. He is also a Chartered Mathematician.
He has published 90+ papers in refereed journals, 10+ book chapters.
