| Abstract | The indentation simulation of the nanocrystalline Ni is carried out by molecular dynamics technique (MD) to study the mechanical behavior at nanometer scales. The sphere indenter is used, and simulation sample with three grains and two grain boundaries is adopted. The strength of nanocrystalline is studied as indenter is set at grain boundary and grain, respectively. Some defects such as dislocations or slipping deformation are observed It is found that dislocations are emitted from the grain boundary or the sample surface. The temperature distribution of local region indenter is analyzed and it can explain our MD simulation results. |
