Fig.4. Circumferential dependences of stress tensor components 22  and 12  on the polar angle: the blue points show the stresses from the atomistic simulations and the red lines show the theoretical results   0.01 e M  .

Fig.5. Circumferential dependences of stress tensor component 11  on the polar angle: the blue points show the stresses from the atomistic simulations and the red lines show the theoretical results   0.01 e M  . The results of MD calculations for aluminum and a comparison of the results for copper and aluminum for the single edge plates are shown in figs. 6 and 7. Figures 6 and 7 show the similarity of the stress distribution at the top of the notch in samples made of two different materials and the similarity of the atomic distributions with stress distributions given by analytical and numerical solutions of classical fracture mechanics.
