Project: On the shock compression response of single crystal tin

4-year DPhil studentship
Supervisor: Professor Daniel Eakins

Tin is a material of considerable interest to the high-pressure and shock communities, owing to its rich sequence of structural phase transitions upon compression. For example, when subjected to shock-loading at modest pressures (< 10 GPa), tin undergoes a transition between two low symmetry BCT phases, resulting in ~10% volume contraction as well as significant microstructural changes. Understanding the effect of these physical changes on subsequent mechanical behaviour is therefore key to the development of predictive models for materials under complex loading.

This project will investigate the response of single crystals of tin to dynamic loading, with particular attention to the link between crystal orientation, transition threshold, and behaviour under reloading/release. The project will involve compression tests from quasi-static to shock strain-rates, employing state-of-the-art techniques (e.g. high-speed imaging/image correlation, laser interferometry) to reveal details of constitutive behavior. These in-house experiments will also be complemented by experiments at 3rd/4th generation synchrotron facilities (e.g. APS, ESRF), for example using the new impact/multi-MHz imaging systems developed by the Oxford team to directly monitor structural changes in real-time. The outputs of this research would be of considerable benefit to the understanding of shock-induced phase changes, both in terms of tin and more generally where materials undergo similar response.

This project offers the opportunity to undertake ground-breaking research in the field of shock-physics, involving elements of materials science, mechanics, and ultrafast diagnostics.
