of austenitic chromium-

environment and chloride concentrations in the corrosive environment were

determined.

All theoretical developments of the thesis are brought to a concrete engineering

technique and algorithms with the application of the offered information technology

of estimation and forecasting of safe operation of elements of the power equipment

taking into account action of the operating environment.

Developed models and methods, information, and software were used in the

Karpenko Physico-Mechanical Institute of NAS of Ukraine, during the

implementation of the project of National Academy of Sciences of Ukraine III-144-

18 in the Department of Strength of Materials and Structures in Hydrogen-Containing

Environments (State Registration 0118U000464, 2018 - 2020).

The practical value of the thesis consists in that developed theoretical and

experimental approach on a modern scientific and methodological basis and the

creation of tools for rapid diagnosis of equipment allow to predict its reliability and

durability considering operating conditions.
The research results were published in 15 scientific works, in particular: 5

articles in scientific professional publications (4 of them in periodicals of other OECD
countries and/or the European Union, professional publications of Ukraine of

category "A", or foreign publications included in the international scientometric
databases WoS or Scopus), 10 abstracts and reports in the conference proceedings.

Keywords: metal hydrogenation, hydrogen concentration, corrosive

environment, creep, stress-strain state, deformation energy, energy approach,

damage, durability.
