The deformation theory and the flow theory of plasticity were compared with experiments of plastic deformation, under the variable stress ratios, by means of vectors of shearing strains and stresses on the plane of octahedron. The shearing strains given by both theories do not show sufficient agreement with those given by the experiments. Then it may be supposed that anisotropy grows in the material as its deformation increases. An orthotropic relation between the plastic strain and stress was derived from generalized type of the flow theory under the condition of incompressibility of plastic deformation. The factors multiplied by the principal stress in the relation, are not only functions of the strain history, but functions of the next new stress ratio.
