Abstract
The molecular dynamics simulations of a screw dislocation in copper and aluminum have been made on the basis of embedded atom method. The configuration and the motion of dislocations under the applied stress were investigated by means of the Burgers vector density. The Peierls stress for a dislocation in copper was estimated to be τ P ∼ 3 × 10 −5 μ, where μ is the shear modulus.
