Current Research Interests
My main aim is to investigate the mechanical behaviour of engineering materials, in particular fracture and strain.
Imaging and diffraction are important tools to help understand the mechanical properties of engineering materials. X-ray imaging techniques enable us to evaluate the three-dimensional structure of a material on a micrometer scale and permit to study quasi-dynamic processes such as deformation fracture propagation. Diffraction techniques allow us to gain insight to the strains and stresses inside a material. My research concentrates on combining synchrotron imaging and diffraction to investigate the deformation, fracture and failure mechanisms on a microstructural level in engineering materials.
One of my current projects with University of Bristol involves studying the fracture behaviour of components, using micro-tomography and digital volume correlation. The combination of these two techniques allows us to measure displacements, and hence deformation, within the material, eg. during micro-indentation. The experimental results are then used to validate complex finite element models, with the aim to gain deeper understanding how damage will develop under real conditions of service.
Since joining the B11 DIAD beamline, I conconcentrate on designing and building a beamline for Dual Imaging and Diffraction, in close collaboration with the Engineering Team and the User Community
