Anisotropy Behavior of Dislocation Nucleation from a Sharp Corner in Copper
Journal of Computational Science and Technology
By means of reaction pathway analysis, we have investigated the nucleation of 90 • and 30 • partial dislocation from a sharp corner in an f.c.c. crystal copper. The anisotropy aspects of dislocation nucleation revealed by the results have shown that the stressdependent activation energy of 30 • partial dislocation is approximately twice over the counterpart of 90 • partial dislocation, and that the maximum inelastic displacement for the former is also higher. Moreover, the shape of thedoi:10.1299/jcst.5.54 fatcat:oz3vbiw2lbchnh4evskacbqg7e
