The motion of dislocations was studied by means of molecular dynamics simulations. The embedded atom method potential was used to express the non-central nature of atomic interactions in metals. A new embedded atom method potential, which could be expressed in terms of simple functions, was developed and used in the simulation. The equilibrium configurations of atoms, and the motion of dislocations in Cu and Ag crystals, were investigated. The Peierls potential was estimated from the change in the kinetic energy and position of the dislocation.
