Staff from the Higher School of Mechanics and Control Processes of the PhysMechanics Institute (PhysMechanics) participated in the International Scientific Symposium on the Problems of Mechanics of Deformable Solids, dedicated to the 115th anniversary of the birth of Corresponding Member of the Russian Academy of Sciences Alexei Ilyushin (1911–1998). The event was held at Lomonosov Moscow State University.
Alexey Ilyushin was a prominent Soviet and Russian mechanical engineer of the 20th century. He developed the theory of elastic-plastic processes and was one of the founders of the modern theory of constitutive equations in continuum mechanics. He was the author of numerous scientific inventions, the founder of several scientific schools in mechanics, and the director of important state scientific and technical projects. He was a Corresponding Member of the Russian Academy of Sciences, a member of the Russian Academy of Rocket and Artillery Sciences, and a laureate of the Stalin Prize (1948) and the Lomonosov Prize, First Class (1995). He was Rector of Leningrad State University from 1950 to 1952. He also served as Head of the Elasticity Theory Department at Moscow University from 1942 to 1998. Over 150 dissertations were defended under Alexey Ilyushin's supervision.
The International Scientific Symposium in Memory of Alexey Ilyushin was held for the sixth time. It was organized by Lomonosov Moscow State University, the Russian Academy of Sciences, and the National Committee on Theoretical and Applied Mechanics.
The symposium's theme corresponded to the scientist's main scientific interests, covering a wide range of modern problems in the mechanics of deformable bodies.
More than 100 scientists from Russia, Belarus, Slovenia, Armenia, and Uzbekistan participated in the forum. Four RAS academicians participated: I. G. Goryacheva, R. I. Nigmatulin, Yu. V. Petrov, and V. A. Sadovnichy. The symposium program included 70 oral presentations.
SPbPU scientists presented four reports.
A. S. Semenov, D. A. Dron, Ya. K. Astapov: "Effective elastic and inelastic properties of porous metal-ceramic electrodes of solid oxide fuel cells". A. I. Grishchenko, A. S. Semenov: "Interaction of different slip systems during inelastic deformation of single-crystal nickel-based alloys". P. V. Vinh, A. B. Freidin: Static bending and buckling analysis of nanoplates using modified nonlocal strain gradient theory. S. A. Vavilov, L. V. Shtukin, O. V. Privalova, D. S. Vavilov, A. A. Kudryavtsev: "On modal localization in a string on an elastic foundation".
The report by A. I. Grishchenko and A. S. Semenov contained the results of research obtained within the framework of the RSF grant No. 25-19-00921 “Multiscale microstructural models of inelastic deformation and fracture of single- and polycrystalline heat-resistant alloys under complex thermomechanical loadingThe results presented were highly praised by participants in the section "Plasticity. Thermodynamic Processes. Theory of Constitutive Relations."
Professor Artem Semenov commented on his participation in the symposium: "This is a wonderful opportunity to see how professionals react to new ideas and research results, to receive valuable recommendations for their further development, to see the direction of development in domestic mechanics, and to informally connect with long-time friends and colleagues."
Professor Alexander Freidin noted: "The symposium was attended by leading mechanical scientists. I was delighted to see my colleagues and friends and to participate in the discussion of the papers. Our Vietnamese graduate student, Pham Van Vinh, presented results that will be included in his PhD thesis, and this was an important preliminary work."
"I was pleased to present the results of my research to leading scientists in the field of solid mechanics and to communicate informally with leading scientists from Russia, Belarus, Serbia, and Armenia," commented Senior Lecturer Alexey Grishchenko.
Polytechnicians remembered the forum for its vibrant presentations by leading scientists, heated discussions and exchanges of opinions, and interesting facts from the biography of A. A. Ilyushin.
