    Abstract In this study, molecular dynamics simulations were performed to study the uniaxial compression deformation of magnesium nanopillars with square and triangular surface notches. The generation and evolution process of internal defects of magnesium nanopillars was analyzed in detail. The results indicated that the triangular notches had little effect on the deformation behavior of magnesium nanopillars, and the governing mechanism of plastic deformation was the initiation and motion of pyramidal dislocations. As for magnesium nanopillars with square notches, the initial plastic deformation was mainly caused by the pyramidal slip. After the notches were closed, {10̅11} <10̅12> twins More >
