• Continuum damage mechanics has been applied to develop a constitutive equation which expresses the strain-time relation for the weakening effects occurring during long-term creep, caused by processes such as cavity formation and precipitate coarsening. Stress-life relations have been developed in a similar manner. This approach was found to accurately describe and predict creep curves as well as the rupture lives of low alloy steels. It is shown that long-life creep rupture and the time to achieve the minimum creep rate may be predicted satisfactorily from short-term tests.
