Profile

Christophe Pinna obtained his PhD from Ecole Polytechnique in France in 1997 in the field of fatigue and fracture. He joined the Department in 1998 as a post-doctoral Research Associate and started to work on the thermo-mechanical processing of metals. He became Research Fellow the same year and Lecturer in 2000. He was promoted to Senior Lecturer in 2008.

Areas of Research

Dr Pinna's research activities are in the fields of mechanics of materials, experimental mechanics and computational solid mechanics applied to the areas of the thermo-mechanical processing of metals (including forging, rolling and friction stir welding), composites, fatigue, damage and fracture as well as machining. The work involves multi-scale experiments at both room and elevated temperatures using conventional as well as small-scale testing machines (tensile and bending inside a Scanning Electron Microscope).

Full-field strain measurement techniques including optical 3D Digital Image Correlation, Scanning Electron Microscopy-based Digital Image Correlation and microgrids generated using electron lithography are being used to quantify strain distributions in specimens as well as over representative areas of microstructures.

Modelling techniques involve finite element models (including implicit/explicit, arbitrary Langrangian-Eulerian and XFEM formulations) combined with cellular automata for damage modelling as well as crystal plasticity finite element models coupled with phase-field models for simulations of microstructure deformation and evolution (recrystallization and phase transformations including texture prediction).

Projects are funded through grants from EPSRC, the European Union and industry.
