Profile

Matthew Marshall is a lecturer in tribology in the Department of Mechanical Engineering. He has a first class degree in Mechanical Engineering from the University of Sheffield and a PhD in Tribology.

Upon completion of his PhD, Matthew worked for the Advanced Manufacturing Research Centre (AMRC), undertaking research work on behalf of Rolls-Royce investigating the manufacture of aero-engine casings in heat resistant super-alloys.

He joined the department in December 2008, and works within a tribology group that specialises in industrial wear and lubrication problems, as well as in the development of metrology tools for tribology. Matthew teaches Tribology of Machine Elements to undergraduate and postgraduate students.

Research interests

Matthew's research work covers a range of industrial friction, wear, and contact mechanics problems. This work involves a range of experimental as well as analytical techniques, and in many cases includes the testing of full scale engineering components.

One research theme has focused on tribology in aero-engines, with specific work undertaken investigating the contact mechanics and wear of abradable linings in compressors. This work has been performed in conjunction with Rolls-Royce, and has involved the development of a novel test platform capable of accelerating compressor blades to velocities in excess of 100 m/s.

Recently, this work has been extended to consider the use of composite materials as linings in certain shaft based applications.

Another activity is concerned with manufacturing tribology, and the measurement of friction from cutting tools. At present this work has focused on the development of a novel lathe based friction test device; where testing is performed at high speeds in order to replicate actual cutting conditions.

The information gather through this type of testing is useful in the selection of coatings for cutting tool inserts, as well as in determining appropriate cutting fluids for a given application.

During his post-graduate study Matthew researched the use of ultrasound as a non-intrusive technique for quantifying the contact pressure distribution in a variety of machine tool contacts. To date contact mechanics and ultrasound remains an area within which he is an active researcher.

His work has focused on a range of contacts including; the rail / wheel contact in railway applications, interfacial pressure distributions in bolted joints, and stresses developed at the interface in simple interference fits.

This work culminated in the application of the technique to a full size railway wheel-set, where the contact pressures in the interface between the wheel and the axel were quantified for both a new and existing wheel-set, in order to validate FE modelling results. Recently, Matthew has been involved in applying this technique to dynamic contacts.
