Fig. 6

Growth in the transverse direction of a \((10\bar {1}{2})\) twin. The twin is modelled by a dipole of disclination loops (red solid lines) and gowth as per application of a shear strain ε₂₃ of 0.01. From (a) to (d): progressive growth of the twin. The arrows show the applied shear in figure (a). In blue colour is shown the plastic rotation around X₁. Only plastic rotation values smaller than -0.06 rad are shown
