Abstract
A creep life model of the blade has been studied out of consideration for scientific management of gas turbine. The paper has studied creep constitutive equation alternatively for each creep stage based on the classical creep curve. It has been find that there is no the second stage of creep when material under the condition of higher stress. Then judgment criterion has been proposed to deal with that phenomenon. Different creep constitutive equations of coupled damage have been derived for different stress level .Finally, comparison of experimental results with creep model has been made to validate it.
