Self-relaxation of twin stacks. Initial twin stacks are let to self-relax by thickening/thinning of twins in the normal direction. a: sketch of the simulated twin stacks using wedge disclination lines. b: Colour-coded is shown the initial in plane shear stress field (MPa) due to disclination lines (red lines). c View in the (X1,X3) plane showing the progressive growth and shrinkage of twins during self-relaxation until a defect-free matrix is obtained
