The hydrogen is contained in any material. Its concentration inside the materials leads to mechanical properties degradation. The two‐continuum model of solid allows one to describe the influence of small concentration of hydrogen on the mechanical properties of materials in terms of changing the bonding energy of the second continuum, the latter being responsible for the hydrogen concentration. The application of this model to fatigue task give the hydrogen concentration that are critical for material destruction. Such fatigue destruction has a nature of parametric instability during the cyclic redistribution of the hydrogen under the cyclic loading. (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
