Simulation of molecular dynamics using Embedded Atom Method(EAM) potentials is performed to investigate the mechanical properties of single crystal Al along various crystallographic orientations under tensile loading.The specimens are provided with one or two embedded circular voids to analyze the damage evolution by void growth and coalescence.The simulation result shows that the Young’s modulus,yielding stress and ultimate stress decrease with the emergence of the voids.Besides,the simulations show that the single-crystal Al in different crystallographic orientations behaves differently in elongation deformations.The single-crystal Al with 100 crystallographic orientations has greater ductility than other orientated specimens.The incipient plastic deformation and the stress-strain curves are presented and discussed for further understanding of the mechanical properties of single-crystal Al.
