Numerical modelling on deformation and recrystallisation in ice

The movies illustrate the 2D microstructure evolution under pure shear deformation in terms of crystallographic preferred orientations, dislocation densities and local strain rates. The numerical simulations are used to investigate the relevance of the process of grain dissection for ice microdynamics.
