000015311 520__ $$2eng$$aA general approach to modeling the effect of hydrogen on stress-strain state of materials is addressed. A twocontinua model is constructed which allows one to describe the kinetics of hydrogen in metals. The developed rheological model is appropriate for estimation of the hydrogen transition from mobile to bounded state depending on the stress-state relation and description of the localization of the connected hydrogen that results in the material fracture. A novel approach to modeling the solids with account for the influence of hydrogen on the properties of free surface on monocrystals at various scales is suggested. One of the most challenging problems of the material science is the influence of hydrogen on the mechanical properties of materials. This influence itself is a good example of crucial importance of small parameter in mechanics since the mean mass concentration of 0.4-0.8 ppm (part per million) causes hydrogen embrittlement in aluminum alloys. The hydrogen embrittlement is a source of many technical catastrophes and for this reason its nature is carefully investigated, e.g. [1].
