Abstract
A model of creep-induced fracture in the three-dimensional stress state is developed on the basis of analysis of the initiation and growth of pores caused by plastic deformation and the diffusion of vacancies; calculations of the critical strain and longevity of specimens in the uniaxial and three-dimensional stress states are performed using this model. Comparison of the results with experimental data illustrates their satisfactory correspondence.
