An extension of a previous work is presented in which a theoretical model of interacting atomic chains (IACs) was proposed which represents a multi‐dimensional (two‐ or three‐dimensional) generalization of the classical Frenkel‐Kontorova (discrete sine‐Gordon) model. The previous paper considered the application of the IACs model to the description of the crowdion in anisotropic crystals. Now we prove that this model can be used for computer simulations of edge dislocations. The computer calculated data agree well with analytical results of elasticity theory. The IACs model is compared to other theoretical models proposed in the literature to describe dislocations in the crystal.
