Michael E. Rutherford (ISP AWE-CASE PhD Student)
Supervisor: Dr. Daniel Eakins
Michael is a first year PhD student within the ISP supported by the EPSRC and AWE. His research is focussed on developing and applying X-ray based imaging techniques to study sub-surface deformation in shock-compressed materials.
For many years, the existence and evolution of sub-surface processes responsible for the bulk material behaviour of materials during dynamic loading has often been inferred from surface-based measurements during compression or the microstructural characterisation of recovered material. Accordingly, the extreme conditions community is heavily reliant upon numerical models for its understanding of early and intermediate stage damage processes such as heterogeneous densification, crack propagation, pore collapse, and ejecta formation.
Michael's research intends to make novel observations of sub-surface material dynamics using the high-resolution capabilities of modern X-ray sources, and use this data to validate existing materials models, thereby assisting in the development of next generation, better-performing materials.
