Overview
Marine Research Group
Applications are invited for a fully-funded 3-year PhD studentship sponsored by UCL (Impact Studentship Scheme), Lloyd's Register and the Ministry of Defence (UK).
The Project: Protection of ships against the threat of an air-blast as a result of hostile actions requires a multi-hazard approach to design involving a complex series of trade-offs that must be balanced against other design constraints spelled out in the ship design rules. The traditional strategy to counter blast and impact threats is to deploy thicker blast shields or armour plating with special reinforcements to protect against projectiles fired from different weaponry. However, recent trends have moved towards more cost-effective, high-strength and lightweight strategy that reduces weight without compromising cost, performance and safety. Components used to resist blast and impact should now also be ultra-light because this saves energy, fuel and while contributing positively to the low carbon (or 'green') agenda, reduces costs and lead to higher performance.
It is well-known that, in addition to the primary effect of ambient over-pressure, an air explosion also produces fragments and missiles leading to perforation and blast ingression into adjacent ship compartments or to the existing structure it protects. The blast wave interacting with, and loading the fragments, causes damage to the panels synergistically which involves highly non-linear transient phenomena. This project would use a combination of experiments and modelling to study, for the first time, the response of the proposed lightweight, blast resistant sandwich systems to protect critical ship compartments against the combined effects of blast and fragment loading. The aim is to develop a methodology to simulate numerically the synergistic interactions and explore novel combinations of 'micro-architectured' core topological construction with different combinations of composite/ceramic face for combined shock and fragment mitigation. Performance charts for different core topologies and face sheet materials against combined blast and fragment threats would be formulated.
Eligible candidates
: Applicants should have obtained (or expect to be awarded) a First or upper 2:1 degree in mechanical/civil/general engineering, applied mathematics, physics, or a related discipline.
Closing Date and Start Date: 15th July 2010 and 1st Oct 2010 (or earlier by agreement).
Value of award: Full tuition fees and stipend of up to £15,363 per annum. Note that resident requirements as spelled out in http://www.epsrc.ac.uk/funding/students/Pages/eligibility.aspx apply.
Contacts: Interested candidates are strongly encouraged to contact Dr. PJ Tan (pj.tan@ucl.ac.uk) for an informal discussion.
All other enquiries on application and admission contact Dr. William Suen (k_suen@meng.ucl.ac.uk). Refer to http://www.ucl.ac.uk/admission/graduate-study/application-admission/ for a formal application pack. Please include a CV and cover letter stating how the project meets your research interests.
A copy of your application should also be sent (in addition to the formal application submitted to UCL Graduate School), via email (pj.tan@ucl.ac.uk) or post, to:
