Abstract
The structure of coaxial, or Eshelby, dislocations are computed using isotropic elasticity for arrays of up to 500 dislocations. The energies of these arrays are determined in order to predict the lowest energy configuration and multiple meta-stable configurations are often found. The energy from these elasticity predictions shows good agreement with molecular statics simulations of aluminum. From these simulations, the torque-twist curves are predicted and compared with molecular dynamics simulations.
