Abstract
The asymptotic solution to Mode III and Mode I crack problems in a creeping solid in the framework of Continuum Damage Mechanics is presented. The kinetic law of damage evolution is the Kachanov — Rabotnov equation [1]. The damage parameter is incorporated into the power-law creep constitutive equations. Thus the coupled system of damage mechanics — creep theory equations is considered. It is to be expected during such a coupling process that the damage involved gives a great effect on the stress field near the crack tip and when the damage parameter reaches its critical value a totally damaged zone near the crack tip may occur [2, 3, 4].
