Abstract
Motion of dislocations was studied by means of molecular dynamics simulation. The embedded atom method (EAM) potential is used to express the non-central nature of atomic interaction in metals. A new EAM potential expressed by simple functions has been developed and used in the simulation. The equilibrium configuration of atoms and the motion of dislocations in Cu and Ag crystals were carefully investigated. From the change of the kinetic energy and the position of the dislocation, the Peierls potential was estimated.
