Atomistic Calculation of Peierls-Nabarro Stress in a Planar Square Lattice

  • W. R. Tyson

Abstract

Fully atomistic calculations for an edge dislocation have been performed using an empirical pairwise potential bonding atoms in a planar square array. The lattice friction stress for motion of a <10> dislocation is much larger than the Peierls-Nabarro result and consistent with more recent theoretical approximations.
