Specialisation: Computational solid mechanics, small-scale plasticity, dislocation dynamics
Comparing the dwell-sensitivity of two different Ti alloy microstructures. (From work with colleagues at Imperial College London; please click here to view the article)
My research focuses on using planar Discrete Dislocation Plasticity simulations to investigate the micro-mechanism of various plastic deformation phenomena, including the Bauschinger effect in small, confined volumes; dislocation mobility effects in BCC materials; and strain rate and dwell sensitivity in Titanium alloys used in the aerospace industry.
During my work, I have also developed expertise in the X-FEM method and crystal plasticity FE modelling.
