3.2. Atomic and particle arrangements during loading and unloading The atomic arrangement during indentation as determined by MD simulations is seen in Fig. 5 and the corresponding particle arrangement obtained from PD simulations in Fig. 6. Orientation [010] is shown to the left in Figs 5,6, and orientation [011] to the right. displacement = 1 a 0 displacement = 1 a 0

displacement = 2 a 0

displacement = 2 a 0

displacement = 3 a 0

displacement = 3 a 0
