review text: An analysis is provided of the finite strains of rotating disks followed by damage and creep rupture front motion as described by Kachanov's hypothesis. The creep is represented by the generalized Norton-Odqvist law for the true stresses and logarithmic strains. An iterative method of solution is proposed. It allows for the inclusion of inertia forces in the formulation of equilibrium. Two numerical examples illustrate the deformation process, ductile and ductile-brittle creep rupture.
