Abstract Based on the concept of the effective stress in continuum damage mechanics, this paper studies the damage-coupled problem in elastoplastic creep. By using the parametric variational principle developed from optimal control theory, a numerical principle for the problem discussed has been established, the proof for which is also given. It is found that the principle proposed has a normalized form and can easily be put into application by computer.
