Participation in a Scientific Conference

9.3.2026

The Associate Professor of the Department of Professional Education, Restaurant and Tourism Business, Candidate of Technical Sciences Valerii Kolesnikov took part in the 7th International conference “Fracture mechanics of materials and structural integrity.”

The conference was held at the G.V. Karpenko Institute of Physics and Mechanics of the NAS of Ukraine from March 3 to 5, 2026. Valerii Oleksandrovych Kolesnikov, together with Professor, Doctor of Technical Sciences, Leading Researcher of the Department of Strength of Materials and Structures in Hydrogen-Containing Environments at the G.V. Karpenko Institute of Physics and Mechanics of the NAS of Ukraine, Oleksandr Ivanovych Balytskyi, prepared a presentation and report on the topic: “Fracture mechanics approaches for advanced repair technologies of damaged hydrogen cooled turbogenerator rotors (review)”.

The conference was held under the auspices of the European Structural Integrity Society (ESIS). The conference was co-organized by the G.V. Karpenko Institute of Physics and Mechanics of the NAS of Ukraine, the Ukrainian Society for Fracture Mechanics of Materials, and the Western Scientific Center of the NAS of Ukraine and the Ministry of Education and Science of Ukraine.

The conference was dedicated to the 100th anniversary of the birth of an outstanding scientist in the field of fracture mechanics of materials and strength of structures – Academician of the National Academy of Sciences of Ukraine Volodymyr Panasiuk (1926-2026).

The conference was opened and welcomed by its chairman – Academician of the National Academy of Sciences of Ukraine Zinovii ​​Nazarchuk. After that, a report was delivered: “Academician of the National Academy of Sciences of Ukraine Volodymyr Panasiuk and his contribution to the development of fracture mechanics and strength of materials” (corresponding member of the National Academy of Sciences of Ukraine Ihor Dmytrah).

The conference program included six thematic areas:

• fracture and strength of materials;
• mathematical methods and modeling of fracture;
• fracture in the presence of aggressive environments;
• integrity of structures;
• non-destructive methods for assessing the defectivity of materials;
• applied aspects of fracture mechanics.

In total, 51 scientific reports and 22 short scientific communications were heard and discussed.

Among the speakers and co-authors were representatives of 18 countries, including: Great Britain, France, Germany, Italy, Spain, Belgium, Canada, Poland, Hungary, Slovakia, Mexico, Azerbaijan, Indonesia, etc.

It should be noted that on February 5, 2026, the G.V. Karpenko Physics and Mechanics Institute was visited by representatives of the Ministry of Education and Science of Ukraine: Deputy Minister of Education and Science of Ukraine Denys Kurbatov and Director General of the Directorate for the Development of Science of the Ministry of Education and Science of Ukraine Hryhoriy Mozolevych. Representatives of the Ministry of Education and Science talked with the administration of the FMI. The key was the meeting with the scientists of the Institute. The Deputy Minister Denys Kurbatov told the administration and scientists of the Institute about the new model of financing the scientific sphere.

We note the fruitful cooperation between Luhansk Taras Shevchenko National University and the G.V. Karpenko Physics and Mechanics Institute of the NAS of Ukraine. This year, a patent for a utility model was obtained:

Kolesnikov V.O., Burdun V.V., Balytskyi O.I., Havryliuk M.R., Kolesnikova Ye.B. A method for obtaining digital images and identifying linear dimensions of microstructures of ferritic-pearlite rotor steels on them: pat. 161794 Ukraine / SI “Luhansk Taras Shevchenko National University”. MPK G01B21/00, G01N15/0227. No. u202400398; appl. 24.01.2024; publ. 07.01.2026, bull. No. 1/2026.

The utility model relates to methods for obtaining digital images and identifying linear dimensions of microstructures of ferritic-pearlite rotor steels on them, both for sections obtained from unused material and those that have undergone prolonged operation under conditions of exposure to hydrogen-containing technological environments at elevated temperatures, and can be used for objective assessment of linear dimensions of structural components of ferritic-pearlite steels for further diagnostics of the reliability and durability of the state of the turbo unit.
