MOLECULAR DYNAMICS SIMULATIONS OF VOID EFFECT OF COPPER NANOCUBES UNDER TRIAXIAL TENSIONS
The mechanical properties of copper nanocubes with cubic voids of different sizes under triaxial tension are studied.In addition to the void size, the effects of different crystal orientations are also taken into account.The mechanical properties of 110 oriented copper nanocubes with voids are investigated from the perspectives of energy, stress and deformation.The difference in crystal orientation can lead to difference in triaxial stress.No matter which direction of the stress, with the increasing size of void, it becomes smaller.For the two kinds of crystalline copper nanocubes considered, the larger the void size, the easier and more regular the destruction of the model.
