Bragg Edge Neutron Strain Tomography
Bragg edge strain imaging from energy-resolved neutron transmission measurements poses an interesting tomography problem. The solution to this problem will allow the reconstruction of detailed stress and strain distributions within polycrystalline solids from sets of Bragg edge strain images. The current state of the art consists of several competing methods to reconstruct the strain, none of which have been proven to work best.
The project aims to build a general approach to reconstruction of an arbitrary system based on a finite element approach with a least-squares process constrained by equilibrium. The project will build on an already existing algorithm and will compare the developed results with experimental measurements made using neutrons at experimental facilities in Australia and Japan.

Thomas is a third-year undergraduate student, currently undertaking a combined Bachelor of Mathematics and Bachelor of Science degree program at the University of Newcastle. He is majoring in Pure Mathematics and Physics, both of which are areas of great interest to him. Tom aspires follow on with postgraduate research after he completes his undergraduate program.
Tom holds particular interest in quantum physics and mathematical modelling, and hopes to further investigate these fascinating subjects in future study. His hobbies exterior to academic studies include running, surfing and reading.
