ABSTRACT
The simulation of nanoindentation into single nickel crystal is performed by
using quasi continuum method. The strain energy-displacement and
load-displacement curves are presented to study the mechanical behavior of the
dislocation nucleation. The characteristics of the stacking fault and
dislocation nucleation are determined by calculating the centro-symmetry
parameters and analyzing the displacement field of the atoms beneath the
indenter. The structure of the stacking fault and the characteristics of
dislocation obtained in the simulation by quasicontinuum method are reproduced
in the simulation by molecular dynamics.
