About the Project
The proposed work is a part of the bigger project whose aim is to develop a physics based multiscale computational framework which accounts for real life physical mechanisms. Aim is to develop a computational model which can directly take actual microstructural data from experiments and predict the microstructure evolution along with deformation, damage nucleation and propagation in such materials during manufacturing and in-service.
Recent studies [1–3] have shown that high strength aerospace alloys show extensive twinning and lattice rotation during deformation while some of the alloys show deformation induced phase transformation causing a change in deformation behaviour.
Things get more complicated once damage starts to nucleate and start to form microvoids, and cracks. The evolution of these defects and foreign particles changes the evolution of phase transformation and vice versa.
Therefore, it is necessary to develop a realistic multiscale computational framework which can take into account the actual microstructural data from experiments and predict the microstructure evolution along with damage nucleation and propagation in such materials during metal forming process.
This PhD work will be aimed at developing a multiscale computational framework to account for the effect of damage nucleation and evolution on phase transformation and transformation induced plasticity and vice versa during metal forming processes.
Candidates should have (or expect to achieve) the UK honours degree at 2.1 or above (or equivalent) in Mechanical or Civil Engineering. It is essential that the applicant has an Engineering or Applied physics background with knowledge of CAD and FE based modelling along with knowledge ofMetal additive manufacturing processes, Material Characterisation, Computational Mechanics, Crystal Plasticity.
