On this basis the analytical-numerical algorithm for calculation of hydrogen concentration redistribution at the stress concentrators in the material depending on the applied external loads was developed. The corresponding numerical assessments have been made for some typical stress concentrators (circular and elliptical holes) and also for crack-like defects.
