Fig. 5From: Microstructure evolution in deformed polycrystals predicted by a diffuse interface Cosserat approachThe 32 grain microstructure before and after applied shear deformation. The initial values are shown to the left for \(\theta \) (top), \(\phi \) (middle) and curvature \(|\nabla \theta |\) (bottom). Top right shows the orientation distribution after shear deformation, middle right shows the corresponding phase-field \(\phi \) and bottom right shows the curvature. The true maximum value of the curvature norm is around \(|\nabla \theta |=1.7\)Ā \(\upmu \mathrm {m}^{-1}\) but it has been capped off at 1Ā \(\upmu \mathrm {m}^{-1}\) for a better visualization. In the simulation, only one slip system was active, resulting in the formation of kink bands and subgrainsBack to article page
