Clive Siviour MA MPhys PhD


Fellow of Pembroke College

TEL: 01865 273132


Professor Clive Siviour completed an MPhys (2001) and PhD (2005) in the department of Physics, University of Cambridge, where he worked primarily on measuring the properties of materials under high strain rate deformation using the split Hopkinson bar.

Clive moved to Oxford in October 2005 to take up a Career Development Fellowship in Engineering, and was appointed to his current position in October 2008.


Research Interests

Clive's research investigates the behaviour of materials and structures when subjected to impact loading. Most materials behave very differently when deformed at high speeds, and our research aims to measure this behaviour and to help understand the microscopic causes of rate dependence, with a view to better design and use of materials. We have a particular interest in the development of novel experimental techniques for different materials, and in the use of high speed photography combined with quantitative image analysis. Materials investigated include aerospace alloys (e.g. Titanium), polymers and natural materials, such as silk, this wide range is enabled by extensive collaborations with leading researchers in the fields.

In addition, Clive is a member of the editorial boards for Experimental Mechanics and Strain and has acted as guest editor for special issues of Proc. R. Soc. A. and Journal of Strain Analysis. Clive is regularly on the organising committees for the Society for Experimental Mechanics, APS Shock Compression and DYMAT conferences. In 2015 he took part (with University of Reading) in the Royal Society Summer Science Exhibition, on a stand Materials that Repair Themselves.

In 2016, Clive's contributions to Experimental Mechanics were recognised by an invitation by the Society for Experimental Mechanics to give the JSA Young Investigator plenary lecture at their annual conference.
