Overview

As part of the M2RI and Materials Engineering Research Centre, the Institute of Structural Materials (ISM) is a world leading mechanical characterisation facility at Swansea University, Bay Campus. Our research focuses on understanding the mechanical behaviour of advanced structural materials exposed to extreme conditions, working in close collaboration with companies such as Rolls-Royce (link to RR UTC site), GKN, UKAEA, TIMET to enable the implementation of next generation materials in current and future components. All of the ISM’s mechanical testing is performed under UKAS 17025 accreditation due to our unique partnership with Swansea Materials Research & Testing (SMaRT).

We have world-class expertise in the areas of:

  • Mechanical characterisation of advanced structural materials
  • Academic interpretation of the mechanisms controlling material deformation and fracture

Professor Mark Whittaker's involvement in the partnership with Rolls-Royce is used as a case study by the Research Councils UK.

Our Research Areas

Funding

The UTC is the ‘pump primer’ for access to major research contracts involving the Innovate UK, Engineering and Physical Sciences Research Council (EPSRC) and associated industrial sponsors.

The value of research funding obtained through these combined sources is substantial. Research in progress is consistently exceeding £4M. This supports a pool of highly experienced post-doctoral research officers and support staff.

The front line research being carried out ensures that the academic staff involved in project supervision are able to bring the latest information to a number of undergraduate and postgraduate courses. These form an integral part of the Faculty of Science and Engineering teaching portfolio.
