摘要：

Crack growth and damage in viscoelastic bodies are studied. Using the Sih criterion of fracture the safe and critical loads as well as delaytime of rupture for structure with a crack are determined. Damage is studied on the base of the energy approach. Evolution of damage, the threshold stress, delay time and limiting damage and strain in a rod under action of a constant load are found.
