Disclination models of grain boundaries in crystals are considered. The features of the spatial distribution of the configuration stress fields depending on number of disclinations and magnitude of the common Frank’s vector are described. The estimate of the energy of the configurations based on the calculations in a wide range of values of the bending-torsion tensor 0.2…1.8 degrees per nanometer was obtained. It was shown that the energy of the equidistant model is higher than the energy of the other two with irregular distribution of disclinations.
