About the Project

HCP materials such as titanium and magnesium have low formability at room temperatures and tend to have brittle behaviour during forming. HCP materials have two major deformation mechanisms - slip and twinning - which is very different from FCC materials such as aluminium, which have only one major deformation mechanism which is slip.
With an increase of temperature, the twinning mechanisms become more active giving in this way more formability to the HCP materials. The study of the twinning mechanisms are thus pivotal for the understanding of the formability of these materials.
HCP material have a very good ratio strength/weight and for this reason they are having an increasing use for mechanical and aerospace engineering. The major aim of this PhD project is to use crystal plasticity for the modelling of slip and twinning of HCP materials at room and elevated temperatures and define the best forming conditions for these materials.
Candidates must have some good knowledge on finite element analysis and motivation to develop new models and do programming for an in-house software and also for user material subroutines for Abaqus.

Funding Notes

Brunel offers a number of funding options to research students that help cover the cost of their tuition fees, contribute to living expenses or both. See more information here: Recently the UK Government made available the Doctoral Student Loans of up to £25,000 for UK and EU students and there is some funding available through the Research Councils. Many of our international students benefit from funding provided by their governments or employers. Brunel alumni enjoy tuition fee discounts of 15%.)
