摘要：
We develop a mathematical model of damage accumulation in structural materials under the conditions of creep and corrosion cracking. The model is tested to determine the service life of a rectilinear section of heat exchange pipes of steam generators of nuclear power plants under complex loading. The influence of thickness of the pipes, pressure in the secondary circuit, and chemical composition of corrosive media on the service life of structural elements is established.
