 This paper gives a brief description of several models of the motion of dislocation lines in the simulation region: the principal model of dislocation multiplication of the Frank — Read type and models developed on its basis. The latter include models of a single dislocation motion, multiplication and motion of an ensemble of dislocations, formation of a dislocation pile-up. The paper presents the main results obtained on the basis of these models: the curve of deformation under constant uniaxial loading; the curve of deformation at a constant rate of deformation; the curve of dependence of the number of dislocations in a pile-up on the value of the external applied stress.
Keywords: crystal, defect, dislocation, deformation, ultrasound, differential equation,
model.
