A unified inelastic constitutive equation is proposed to describe the cyclic inelastic deformation of 2 1/4Cr-1Mo steel at 550°C. In the present study, an evolution of the overstress is discussed which leads the time-independent term into the inelastic strain rate. A mathematical model is developed and some examples of the numerical simulation are presented.
