抄録: This paper treats a unified constitutive model for the viscoplastic and creep deformations. First, experimental observations on the correlation between back stress due to plasticity and creep are carried out using Type 304 stainless steel at room temperature. The experimental results show that there is the equivalence of back stress due to plastic and creep deformation. Then considering the equivalence of back stress, a unified constitutive model for plasticity and viscoplasticity is proposed. To verify the applicability of this model, the numerical simulations are conducted by the model, and compared with the experiments.
