摘要：
A mathematical model of damaged media for the degradation processes of initial strength properties of metals and their alloys affected by fatigue and creep is considered. The processes of viscoplastic deformation and damage accumulation in polycrystalline alloys are numerically analyzed. New features of the failure process are noted.
