Assessing of the Life Time of a Shaft with a Crack in Hydrogen
A theoretical-experimental approach for predicting the kinetics of fatigue crack growth and determining the life time of the responsible elements of structures in hydrogen is proposed. Based on the created calculation model of fatigue crack growth, experimentally constructed kinetic diagrams of fatigue failure of 35KhN3MFA steel, the residual life of the rotor shaft of the turbo generator, weakened by a surface semi-elliptical crack in air, and in gaseous hydrogen environment, are determined. Hydrogen reduces the residual life of the rotor shaft by two orders of magnitude in hydrogen, compared to its residual life in air.
期刊介绍：
Materials Science reports on current research into such problems as cracking, fatigue and fracture, especially in active environments as well as corrosion and anticorrosion protection of structural metallic and polymer materials, and the development of new materials.
