Abstract
The stress field of the edge multipole (dipole cluster) in the basal plane is approximated by the superdipole stress field. The stress fields of different dipole (superdipole) arrays are given for anisotropic cadmium crystal. The stress field components into the secondary non-basal slip planes (pyramidal and prismatic) were computed for the same metal. It was shown that the magnitude of this component is comparable with both the value of flow stresses in the secondary systems and the same component of the pile-up stress field.
