PhD Studentship at the University of Southampton, UK:

Development of a Mechanistic Wear Model for Analysing the Performance of Total Knee Replacement



School of Engineering Sciences, University of Southampton



Ref: SES-73-084



A PhD studentship is now available in the Bioengineering Sciences research group, School of Engineering Sciences (SES), which fully covers University tuition fees (at EU/UK level**) and provides a tax-free bursary of 12,940 per year, rising annually in line with the UK Government (EPSRC) recommended rate, for a 3-year duration. ** EU/UK fees 3300 p.a., overseas fee 13,480 p.a. (all figures subject to increase).

The project is open to UK/EU and overseas students. However, overseas students will be required to provide the fees difference of 10,180 from other sources (Please note that the fees might be covered for exceptional overseas applicants).



Project description:

Wear of polyethylene is the limiting factor influencing the longevity of total knee replacement (TKR). Currently wear of TKR designs is assessed through experimental tests, but these are expensive, time consuming and as a consequence are only able to assess a limited range of activities. Recently, computational tools have been developed to simulate wear and the initial results look promising. These fast and efficient tools provide greater flexibility and allow a more rigorous analysis of the wear potential for new implant designs. However, the wear model used in the computational studies is relatively simple, based around an adaptation of a wear algorithm which does not adequately capture the physics of the wear process.



The aim of this project is to develop a mechanistic model of the wear process and to validate this against experimental data from simplified pin-on-disk machines through to knee wear machines. The project will involve a close interaction with the sponsoring company (DePuy International), the Department of Mathematics and the School of Engineering Sciences and requires a person with a background/interest in continuum mechanics, applied mathematics, mathematical and computational modelling techniques, particularly finite element analysis (structural/multiphysics) and/or multi-body dynamics.





About the University of Southampton

The University of Southampton is one of the UK top ten research universities. The School of Engineering Sciences is a top 5* rated research school with an international reputation.

The successful candidate will work with a group of highly motivated first class research students in a multi-disciplinary environment, within the Bioengineering Science Research Group (www.soton.ac.uk/ses/research/bioeng), the newly formed nCATS (www.sotonac.uk/ses/research/nCATS) (created in 2008 from a 9.7 million pounds investment from Industry, EPSRC and the University of Southampton) and the Institute of Complex Systems Simulations (http://www.icss.soton.ac.uk/) (created in 2009 from a 12 million pounds investment from Industry, EPSRC and the University of Southampton).



The School is a diverse community which is committed to creating an inclusive working and learning environment in which all individuals are equally treated and valued, and can achieve their potential. The School considers all studentship applications in relation to academic criteria and regardless of the individual's race, nationality, gender, or belief.





Entry requirements: The studentship is available to candidates with the equivalent of a first class or upper second class degree in relevant disciplines, e.g. applied mathematics, physics, mechanical engineering, biomechanical engineering. The studentship is at the standard EPSRC (Engineering and Physical Sciences Research Council) rate, commencing in 2009.
