Abstract: The article describes a model of interaction dynamics between a dislocation and dipolar dislocation loops. The interaction is essential for dipolar dislocation structure formation in early stages of a hardening process. For the description of the dislocation curve a direct parametric approach is employed whereas the loops are treated as rigid objects. The model equations are solved approximately by means of the finite-volume method. Physically interesting phenomena can be captured by the model provided the simulation covers long time periods. The strong interaction between the dislocation and the loops causes growing nonuniformity of distribution of discrete nodes along the dislocation curve. This effect is balanced by two proposed types of tangential redistribution of the discrete nodes. The redistribution is tested in simulations of loop clustering.
