The subloading surface model was extended so as to describe the cyclic loading behavior pertinently and, based on this model, the constitutive equation of metals was formulated in Part 1. The calculated results by the present model are compared with various cyclic test data for stress and strain amplitudes with one-side and both sides of tension and compression and the circular stress path. Then, it is verified that the present model does not require to incorporate the algorithms for the yield judgment and the pull back of the stress to the yield surface and has the high ability to predict the cyclic loading behavior of metals by introducing the tangential-inelastic strain rate and the stagnation concept of isotropic hardening.
