摘要: The presence of in-homogeneity or defects in materials cannot be ignored. There is great need to understand the influence on mechanical response nano-materials. In this study, atomistic simulations have been used investigate gold nano-wires under twisting. Simulations show that different elastic properties when are present. Embedded cracks sizes created quantify in-homogeneity. inter-atomic interactions represented by employing an embedded-atom potential. effect crack potential energy, torque and stresses for investigating a nano-wire part whole investigation. It predicted from our simulation dimensions control torsional nano-wires. Deviation behavior continuum expectations also discussed. comparison results made with linear elasticity model (of healthy cracked nano-wires) get deep insights into nano-scale
