The article is concerned with finite element solution of hydrogen-induced brittle fracture of a metal cylindrical specimen with a semicircular groove. The study is based on the HEDE model of hydrogen brittleness and considers the skin effect of charging the samples with hydrogen. The results showed that taking into account the skin effect leads to the changes in the mechanisms of destruction of samples, and it can be the true cause of the experimentally observed dual fracture pattern.
