Twinning is an important deformation mechanism and is dominant under certain deformation conditions and in certain materials. In this project, we are trying to develop a multi-scale modelling approach to study twin formation, twin growth and the interactions of twins with other defects.

During phase transformations, the anisotropies in the interfacial energy (thermodynamic) and mobilities (kientic) play a key role in the formation of microstructures. We are trying to incorporate these anisotropies in the phase field models as well as get these parameters from atomistic simulations.

We use atomistic (molecular dynamics and Monte Carlo), as well as continuum (dislocation dynamics and phase field) models (coupled with experiments) to explore the formation of microstructures during mechanical deformation.
