Mobile Dislocation Density and Crystallographic Texture.

The mobile dislocation density and velocity have been related to the crystallographic texture via the evolution equation. This relationship makes it possible, in principle to express the final texture which is developed in a material as a function of a few physical parameters only. Only the basic equations are proposed in this paper. Their numerical solution requires knowledge of the dislocation density and velocity as well as the geometrical parameters of shear bands as a function of deformation for the material considered. However, an analytical solution has been found for the particular case of deformation of a Sachs model.
