The anisotropic microstrain distribution resulting from an isotropic distribution of a field tensor (rank 0 or 2), the latter being connected with strain by an anisotropic property tensor (rank 2 or 4), is analyzed. It is shown that the anisotropy of the resulting line broadening is a direct consequence of the anisotropy of the property tensor. Various physical scenarios leading to such a type of line broadening are discussed.
