Vacancy Reference: BK/07/032
Salary Range: Studentship: EPSRC standard studentship + University and College Fees
Appointment Term: 3.5 years
Closing Date: 28/02/2008
We invite applications for a postgraduate studentship in modelling dislocation ladders in fatigue, funded by EPSRC, to work as part of the 5-year Critical Mass programme (which began in 2006) in “New Frontiers in the Mathematics of Solids” (OxMOS). The studentship will be supervised by Prof Jon Chapman (from the Oxford Centre for Industrial and Applied Mathematics) and will be based at the Mathematical Institute, but will also have regular contact with Prof John Ball (from the Applied Analysis and Mechanics Group), and Prof Endre Suli (from the Numerical Analysis Group).
Local mismatches in the atomic structure of a crystalline material are known as dislocations, and act as line sources of stress. Dislocations move around in a material in response to stress, and may become tangled (this is the basis of the work-hardening of metals). Under cyclic loading of a material such as copper it is observed that “ladders” of dislocations form with a characteristic spacing between regions of high dislocation density (the rungs of the ladders) and regions of near pristine material (the gaps in between). It is thought that these ladders play an important role in the fatigue of the material, but at present there is no mathematical theory which can predict the formation or characteristic scale of these remarkably regular structures.
The OxMOS programme aims to strengthen the mathematical underpinning of modern materials science through the transfer of technology and techniques across areas; to link up with materials scientists, engineers and biologists; and to train a new generation of mathematicians, competent in analysis, modelling and computation, who can effectively interact with scientists from other fields. It will incorporate at least 6 DPhil students and 6 Postdocs along with numerous distinguished visitors. The successful candidate will become a member of The Queen’s College.
The studentship is available from 1 October 2008 and is open to UK/EU and overseas sreftudents, and covers full fees (at the UK/EU rate) and maintenance. Non-EU students will need to make up the difference between the UK/EU and overseas fees rate (the current difference being approximately £7,500). The maintenance stipend is £12,600 this academic year.
Further particulars may be obtained from Sandy Patel at The Mathematical Institute, 24-29 St Giles, Oxford, OX1 3LB, email graduate.studies_at_maths.ox.ac.uk. Applications should include a CV, covering letter, the name and address of three references and the University’s application form for graduate study (note that this requires the attachment of a transcript of your undergraduate degree) and must arrive by lunchtime on 28 February 2008. Ensure that you clearly state the BK reference code for the studentship It is the responsibility of candidates to ensure that their references arrive by the closing date.
The University is an Equal Opportunities Employer.
