A disclinations is a line defect which can be regarded as a dense configuration of many dislocations. Because the wedge-shape discontinuity of disclination makes a high stress field, the disclination essentially has a high strain-energy. However some configuration, such as disclination dipoles, can reduce the strain energy, and this structure can be a promising model of description of grain boundary and other inelastic deformation. And the Generalized force is considered as one of the important evaluation standards of mechanical properties of disclinations in solids. We will focus on the estimation of a generalized Peach Koehler force of each disclination, and discuss the possibility of evolution of disclination structure.
