概要

• 論文の詳細を見る

• Atomistic mechanisms of the initial stage of plasticity during nanoindentation are studied by molecular dynamics simulations for three surface orientations of alumina (Al_2O_3) crystal. The simulations predict significant anisotropy and indentation-depth dependence of the hardness value at the nanometer scale. The nanohardness anisotropy is found to arise from orientation dependent dislocation activities.
