摘要：
The model for describing unidimensional anisothermic deformation, allowing for the damage of the material, is presented. The effect of stresses and temperature on creep strain rate variations is evaluated with the scalar function of damage. The validity of the approach is demonstrated with the creep description for 12Cr-18Ni-Mo steel within rather wide stress and temperature ranges.
