A constitutive model is proposed to describe creep deformation of polycrystalline materials under complex stress and temperature histories. The concept of piecewise linear effective stress - creep strain rate relationship is utilized. A key assumption in this model is that the back stress under a given stress and temperature reaches a saturation point. This saturation point corresponds to the steady state condition.
