The practical value of the thesis is that the experimental-calculation method
developed on a modern scientific and methodological base and the created means

of operational diagnostics of the condition of the equipment make it possible to
predict its reliability and durability, taking into account the operating conditions.

Based on the results of the research, 10 scientific works were published,

including 4 articles in specialized scientific publications (including 2 articles in

periodical scientific publications included in the international scientometric

databases WoS or Scopus), 5 abstracts and reports in collections of conference

materials, 1 author's computer program certificate.

Keywords: local true stresses, local true strains, true stress-strain diagram,

metal hydrogenation, hydrogen concentration, pre-strain, stress-strain state, strain

energy, energy approach, damage, fracture resistance.
