PhD Studentship in Composite Materials
In Situ Calibration of Cohesive Zone Models for Composite Damage
School of Engineering Sciences
University of Southampton
A PhD studentship is now available within the Engineering Materials Research Group, School of Engineering Sciences (SES), which will fully cover University tuition fees (at EU/UK level**) and provide a tax-free bursary of £12,300 per year, rising annually in line with the UK Government (EPSRC) recommended rate, for a three-year duration.
** EU/UK fees are £3,168 p.a. (subject to increase), and the overseas fee is £12,700 (subject to increase). Therefore overseas applicants will need to find the fees difference of £9532.
In Situ Calibration of Cohesive Zone Models for Composite Damage Designing with composite materials remains highly dependent on mechanical testing. This project is focused on replacing such testing by efficient use of simulation and modelling. Cohesive zone models (CZM) are a promising means of meeting these aims. They are readily embedded in finite element models, and yet can capture key failure
mechanisms occurring at several lengthscales. However, these models have not been independently calibrated and therefore have limited predictive capability. This project aims to address this limitation by applying a novel experimental technique, high resolution X-ray tomography (HRXT), to obtain data to allow independent calibration of CZM's. HRXT allows sub-micron resolution through the use of
high-energy synchrotron radiation, so this work will be conducted in collaboration with the European Synchrotron Radiation Facility at Grenoble. Lower resolution work (1-10 µm resolution) will be performed with a lab-scale imager at Southampton University. An existing CZM created by collaborators at Rockwell Scientific will be
used. This can be modified depending on the results of the experimental strain mapping. The problem of notch-tip damage and notched strength will be tackled as it represents a key test case that has proven difficult to model. The project will include computational modelling and experiments. The work will be performed in conjunction with Gurit, a leading materials supplier and Airbus UK.
SES 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 the areas of structure property relationships in materials.
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, 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 engineering science, mathematics or physical science disciplines. The studentship is at the standard EPSRC (Engineering and Physical Sciences Research Council) rate, commencing on 2 October 2006.
