The present paper proposes a new law of anisotropic hardening of plasticity, using an internal time concept developed by the endochronic theory. This report describes a fundamental aspect of the present law, as well as a comparison with the previous experiment involving tension-torsion problems. The present law can accurately predict the shape change of the yield surface with only two parameters of deformation, and as a special application of the present theory, it can also express the vertex effects of the yield surface.
