Mechanical Behaviour of Materials

Biomechanics and Biomaterials

Research overview

We are concerned with the understanding of mechanics and mechanisms in musculoskeletal, cardiovascular and biological systems under physiological loading conditions.

A key interest has been in developing a fundamental understanding of fixation integrity of cemented joint replacement. This includes the development of a unique hip simulator for in vitro fatigue testing of implanted acetabulum; micromechanics studies of bone-cement interface using in situ image-guided failure assessment within microCT and finite element modelling; and mechanical characterisation of scaffolds using digital volume correlation.

This work has been carried out in collaboration with Queen Alexandra Hospital and supported by the MRC, ARUK, the Royal Society and the NHS research fund. Recent developments include experimental and numerical studies of soft tissue response to whole-body vibration; simulation of fluid-structure interaction in blood vessels and its significance in predicting the formation of aneurysm and developing new imaging techniques for applications to biological tissues.
