Applicability of the elaborated constitutive equations of cyclic plasticity proposed by the present authors is discussed in detail. New evolution equations of non linear kinematic hardening of the viscoplastic constitutive models developed in the previous paper with special emphasis on the characteristic expansion of the kinematic hardening range observed in the cyclic hardening of type 316 stainless steel at 400℃ to 500℃ were employed. The predictions of the proposed constitutive equations were compared with the corresponding experimental results of cyclic plasticity for various temperatures and loading conditions. The proposed constitutive equations were found to describe accurately the proportional and non proportional cyclic behavior, in particular the effects of strain amplitude histories, for a wide range of temperatures from room temperature to 700℃.
