The aim of the work is to establish a relationship between the Barkhauzen effect parameters in hydrogenated ferromagnetic material under the influence of the applied changeable external magnetic field and dynamic characteristics of elastic fields conditioned by them; to set maximum value of stress intensity coefficient near the top of the current macro crack in case of scanning hydrogenated ferromagnetic by external magnetic field and features of the formation and development of cracks defects. The method of research - mathematical modeling changes of ferromagnetic solids domain structure and generating processes of magnetoelastic AE (MAE) signals in hydrogenated materials under variable external magnetic field.
