During the plenary session, a fundamental analysis of Academician Oleksandr Dynnyk's legacy was presented by the heads of the Dnipro Scientific Center of the NAS of Ukraine and MES of Ukraine. Member of the Presidium of the NAS of Ukraine, Head of the Center, Director of the M.S. Polyakov Institute of Geotechnical Mechanics of the NAS of Ukraine, Academician Anatoliy Bulat, in his speech, greeted the participants on behalf of the President of the National Academy of Sciences of Ukraine, Academician Anatoliy Zahorodniy, emphasized the epochal significance of the jubilarian's figure for the development of Ukrainian and world science, and highlighted Academician Oleksandr Dynnyk's contribution to the development of mining in southern Ukraine, particularly in solving complex problems of coal and ore deposit development. Acting Director of the Center, Doctor of Technical Sciences Serhiy Dziuba, outlined the panorama of the jubilarian's life and creative path, emphasizing that Academician Oleksandr Dynnyk entered history as the founder of the Ukrainian scientific school of elasticity theory, the founder of the doctrine of rock pressure and the dynamics of mine hoisting ropes.
Special attention was paid by the speakers to Academician Oleksandr Dynnyk's organizational talent during his work at the National Academy of Sciences of Ukraine. The scientist was a member of the Academy Presidium, headed the Department of Technical Sciences, and was the founder of the Department of Elasticity Theory of the Academy, which began as the elasticity theory sector he led within the Institute of Mining Mechanics. His professional path is inseparably connected with the establishment of such powerful scientific institutions as the S.P. Timoshenko Institute of Mechanics of the NAS of Ukraine, the Z.I. Nekrasov Institute of Ferrous Metallurgy of the NAS of Ukraine, and the M.M. Fedorov Research Institute of Mining Mechanics. Additionally, Academician Oleksandr Dynnyk created advanced teaching methods for engineering disciplines, which became the foundation for training specialists at leading universities in Kyiv, Dnipro, and other cities.
The second part of the symposium vividly demonstrated that the ideas of Academician Oleksandr Dynnyk continue to live on in the modern developments of Ukrainian scientists. For example, representatives of Oles Honchar Dnipro National University and the National Technical University "Dnipro Polytechnic" reported on the current state of development of scientific schools in dynamics and strength. Scientists from academic institutes shared results of the latest theoretical and applied research. In particular, specialists from the Kharkiv Institute of Energy Machines and Systems of the NAS of Ukraine, together with colleagues from universities, presented calculations of fluid oscillations in shells using the boundary element method. A joint work of the Y.S. Pidstryhach Institute of Applied Problems of Mechanics and Mathematics of the NAS of Ukraine and the State Enterprise "Design Bureau 'Pivdenne' named after M.K. Yangel" demonstrated new mathematical models of rocket and space technology. Reports on the use of a hybrid approach based on artificial intelligence for predicting the impact of icing on unmanned aerial vehicles and improving the reliability of numerical forecasts in complex mechanical engineering were also topical.
The symposium once again confirmed: the fundamental base laid by Academician Oleksandr Mykolayovych Dynnyk over a century ago remains a reliable foundation for the development of innovative technologies in modern Ukraine.
