description: The given work is devoted to the study of the application of the HEDE model to describe the effect of hydrogen on the mechanical properties of materials. The research set the following goals: 1. Overview of the HEDE model, systematization of publications and restoration of the relationship of the relationships and dependencies used in this mechanism; 2. Development of an algorithm to obtain a numerical solution to the problem of the stress-strain state of the sample in question; 3. Test calculations to assess the accuracy and correctness of the compiled program; 4. Application of the developed algorithm to the solution of the problem of hydrogen embrittlement based on the HEDE mechanism; 5. Assessment of the applicability of the HEDE model to the description of the effect of hydrogen on the mechanical properties of materials. The given work yields a survey of the key model of mechanics that are used to describe the effects of hydrogen embrittlement â HEDE model. We constructed a numerical solution to the problem of the effect of hydrogen on the mechanical properties of a sample. The method was implemented in the Microsoft Visual Studio. As a result, we obtained the dependences of the crack initiation time and the critical level of tensile load on the value of the initial hydrogen concentration. We found that these values strongly depend on the content of the diffusing substance. According to the results, with an increase of the initial concentration of hydrogen in the sample, the length of time before it begins to crack and the tensile load that it can withstand without loss of integrity for a given time decreases. Based on the review and numerical solution of the problem, we concluded that it is impossible to apply the HEDE model to solving real problems of engineering practice.
