Calculation of the Defects Interaction Force with the Ritz Method
The defects are moving with the constant velocity V, on which slow vibrations caused by the interaction is imposed . For very long time nearest-neighbor defects are approaching to each other and then are annihilated. The process of mutual annihilation (confluence) is comparatively fast after the defects have approached close to each other. A single defect frictional force has been found with the help of the Ritz method.
