The constitutive equations of the cubic anisotropic plastic materials are generalized to satisfy the principle of material frame-indifference. The constitutive equations obtained in accordance with the requirement for the plastic flow state are assumed to hold in all states. i. e., the natural unstrained state and the plastic flow state. As an example, the simple extension of the materials is analyzed, and the stress-extension relation is obtained. The result shows a gradual transition from the elastic state to the plastic flow state. The comparison between cubic anisotropic and isotropic materials is discussed briefly.
