Summary

Kinematic hardening model is employed to describe the time-dependent constitutive relation by introducing the effects of recovery as well as hardening. Material parameters appearing in the evolutional equation for the center of yield surface are experimentally determined. Effect of deformation rate on tensile stress-strain diagram and creep curves are numerically calculated, and the results were compared with experimental data.
